• GlassFish Security Realm, Active Directory and Referral

  - by Allan Lykke Christensen

  I've setup up a Security Realm in Glassfish to authenticate against an Active Directory server. The configuration of the realm is as follows: Class Name: com.sun.enterprise.security.auth.realm.ldap.LDAPRealm JAAS context: ldapRealm Directory: ldap://172.16.76.10:389/ Base DN: dc=smallbusiness,dc=local search-filter: (&(objectClass=user)(sAMAccountName=%s)) group-search-filter: (&(objectClass=group)(member=%d)) search-bind-dn: cN=Administrator,CN=Users,dc=smallbusiness,dc=local search-bind-password: abcd1234! The realm is functional and I can log-in, but when ever I log in I get the following error in the log: SEC1106: Error during LDAP search with filter [(&(objectClass=group)(member=CN=Administrator,CN=Users,dc=smallbusiness,dc=local))]. SEC1000: Caught exception. javax.naming.PartialResultException: Unprocessed Continuation Reference(s); remaining name 'dc=smallbusiness,dc=local' at com.sun.jndi.ldap.LdapCtx.processReturnCode(LdapCtx.java:2820) .... .... ldaplm.searcherror While searching for a solution I found that it was recommended to add java.naming.referral=follow to the properties of the realm. However, after I add this it takes 20 minutes for GlassFish to authenticate against Active Directory. I suspect it is a DNS problem on the Active Directory server. The Active Directory server is a vanilla Windows Server 2003 setup in a Virtual Machine. Any help/recommendation is highly appreciated!

• refering Tomcat JNDI datasource in persistence.xml

  - by binary_runner

  in server.xml I've defined global resource (I'm using Tomcat 6): <GlobalNamingResources> <Resource name="jdbc/myds" auth="Container" type="javax.sql.DataSource" maxActive="10" maxIdle="3" maxWait="10000" username="sa" password="" driverClassName="org.h2.Driver" url="jdbc:h2:~/.myds/data/db" /> </GlobalNamingResources> I see in catalina.out that this is bound, so I suppose it's OK. In my web app I have the link to the datasource, I'm not sure it's OK: <Context> <ResourceLink global='jdbc/myds' name='jdbc/myds' type="javax.sql.Datasource"/> </Context> and in application there is persistence.xml : <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0"> <persistence-unit name="oam" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <non-jta-data-source>jdbc/myds</non-jta-data-source> <!-- class definitions here, nothing else --> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/> </properties> </persistence-unit> </persistence> It shuld be OK, but most probably this or the ResourceLink definition is wrong because I'm getting: javax.naming.NameNotFoundException: Name jdbc is not bound in this Context What's wrong and why this does not work ?

• HTTP Basic Authentication with HTTPService Objects in Adobe Flex/AIR

  - by Bob Somers

  I'm trying to request a HTTP resource that requires basic authorization headers from within an Adobe AIR application. I've tried manually adding the headers to the request, as well as using the setRemoteCredentials() method to set them, to no avail. Here's the code: <mx:Script> <![CDATA[ import mx.rpc.events.ResultEvent; import mx.rpc.events.FaultEvent; private function authAndSend(service:HTTPService):void { service.setRemoteCredentials('someusername', 'somepassword'); service.send(); } private function resultHandler(event:ResultEvent):void { apiResult.text = event.result.toString(); } private function resultFailed(event:FaultEvent):void { apiResult.text = event.fault.toString(); } ]]> </mx:Script> <mx:HTTPService id="apiService" url="https://mywebservice.com/someFileThatRequiresBasicAuth.xml" resultFormat="text" result="resultHandler(event)" fault="resultFailed(event)" /> <mx:Button id="apiButton" label="Test API Command" click="authAndSend(apiService)" /> <mx:TextArea id="apiResult" /> However, a standard basic auth dialog box still pops up prompting the user for their username and password. I have a feeling I'm not doing this the right way, but all the info I could find (Flex docs, blogs, Google, etc.) either hasn't worked or was too vague to help. Any black magic, oh Flex gurus? Thanks. EDIT: Changing setRemoteCredentials() to setCredentials() yields the following ActionScript error: [MessagingError message='Authentication not supported on DirectHTTPChannel (no proxy).'] EDIT: Problem solved, after some attention from Adobe. See the posts below for a full explanation. This code will work for HTTP Authentication headers of arbitrary length. import mx.utils.Base64Encoder; private function authAndSend(service:HTTPService):void { var encoder:Base64Encoder = new Base64Encoder(); encoder.insertNewLines = false; // see below for why you need to do this encoder.encode("someusername:somepassword"); service.headers = {Authorization:"Basic " + encoder.toString()}; service.send(); }

• mod_rewrite to nginx rewrite rules

  - by Andrew Bestic

  I have converted most of my Apache HTTPd mod_rewrite rules over to nginx's HttpRewrite module (which calls PHP-FPM via FastCGI on every dynamic request). Simple rules which are defined by hard locations work fine: location = /favicon.ico { rewrite ^(.*)$ /_core/frontend.php?type=ico&file=include__favicon last; } I am still having trouble with regular expressions, which are parsed in mod_rewrite like this (note that I am accepting trailing slashes within the rules, as well as appending the query string to every request): mod_rewrite # File handler RewriteRule ^([a-z0-9-_,+=]+)\.([a-z]+)$ _core/frontend.php?type=$2&file=$1 [QSA,L] # Page handler RewriteRule ^([a-z0-9-_,+=]+)$ _core/frontend.php?route=$1 [QSA,L] RewriteRule ^([a-z0-9-_,+=]+)\/$ _core/frontend.php?route=$1 [QSA,L] RewriteRule ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)$ _core/frontend.php?route=$1/$2 [QSA,L] RewriteRule ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)\/$ _core/frontend.php?route=$1/$2 [QSA,L] RewriteRule ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)$ _core/frontend.php?route=$1/$2/$3 [QSA,L] RewriteRule ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)\/$ _core/frontend.php?route=$1/$2/$3 [QSA,L] I have come up with the following server configuration for the site, but I am met with unmatched rules after parsing a request (eg; GET /user/auth): attempted nginx rewrite location / { # File handler rewrite ^([a-z0-9-_,+=]+)\.([a-z]+)?(.*)$ /_core/frontend.php?type=$2&file=$1&$3 break; # Page handler rewrite ^([a-z0-9-_,+=]+)(\/*)?(.*)$ /_core/frontend.php?route=$1&$2 break; rewrite ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)(\/*)?(.*)$ /_core/frontend.php?route=$1/$2&$3 break; rewrite ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)(\/*)?(.*)$ /_core/frontend.php?route=$1/$2/$3&$4 break; } What would you suggest for dealing with my File Handler (which is just filename.ext), and my Page Handler (which is a unique route request with up to 3 properties defined by a forward slash)? As I haven't gotten a response from this yet, I am also unsure if this will override my PHP parser which is defined with location ~ \.php {}, which is included before these rewrite rules. Bonus points if I can solve the parsing issues without the need to use a new rule for each number of route properties.

• Apache Axis2 1.5.1 and NTLM Authentication

  - by arcticpenguin

  I've browsed all of the discussions here on StackOverflow regarding NTLM and Java, and I can't seem to find the answer. I'll try and be much more specific. Here's some code that returns a client stub that (I hope) is configured for NTLM authentication: ServiceStub getService() { try { ServiceStub stub = new ServiceStub( "http://myserver/some/path/to/webservices.asmx"); // this service is hosted on IIS List<String> ntlmPreferences = new ArrayList<String>(1); ntlmPreferences.add(HttpTransportProperties.Authenticator.NTLM); HttpTransportProperties.Authenticator ntlmAuthenticator = new HttpTransportProperties.Authenticator(); ntlmAuthenticator.setPreemptiveAuthentication(true); ntlmAuthenticator.setAuthSchemes(ntlmPreferences); ntlmAuthenticator.setUsername("me"); ntlmAuthenticator.setHost("localhost"); ntlmAuthenticator.setDomain("mydomain"); Options options = stub._getServiceClient().getOptions(); options.setProperty(HTTPConstants.AUTHENTICATE, ntlmAuthenticator); options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT, "true"); stub._getServiceClient().setOptions(options); return stub; } catch (AxisFault e) { e.printStackTrace(); } return null; } This returns a valid SerivceStub object. When I try to invoke a call on the stub, I see the following in my log: Jun 9, 2010 12:12:22 PM org.apache.commons.httpclient.auth.AuthChallengeProcessor selectAuthScheme INFO: NTLM authentication scheme selected Jun 9, 2010 12:12:22 PM org.apache.commons.httpclient.HttpMethodDirector authenticate SEVERE: Credentials cannot be used for NTLM authentication: org.apache.commons.httpclient.UsernamePasswordCredentials Does anyone have a solution to this issue?

• IIS as proxy to rails/mongrel - force a proxied host to generate REMOTE_USER

  - by rbn

  Hello -- Using Application Request Routing I have IIS 7.5 set up as a reverse proxy to a Mongrel service which is serving a rails app. IIS is set up to use Windows Auth and is working but I cannot access the REMOTE_USER variable in the rails app to get at current user's identity. I have inspected the request object in rails and I don't have any other variables like LOGON_USER, HTTP_REMOTE_USER, AUTH_USER, etc. I am trying to find a way to inject the REMOTE_USER variable into Mongrel's server variables. This post describes what I am looking for using mod_rewrite on Apache but I am having trouble recreating this rule for iis. this is the rewrite rule from the post mentioned above for Apache RewriteEngine On RewriteCond %{LA-U:REMOTE_USER} (.+) RewriteRule . - [E=RU:%1] Header add X-Forwarded-User %{RU}e I tried reproducing the rule in IIS and got a URL Rewrite Module error ("The condition's expression "%{LA-U:REMOTE_USER}" is invalid."). I know I'm probably using Apache syntax where IIS syntax is needed but am not sure how to proceed at this point. Any help greatly appreciated.

• Server http://www.myopenid.com/server responds that the 'check_authentication' call is not valid

  - by viatropos

  I've been struggling with this for a few days now, haven't pinpointed the problem. I am trying to get OpenID to work in Rails 2.3 and Rails 3, using ruby-openid rack-openid open_id_authentication I am logging in using my viatropos.myopenid.com account, but it consistently returns this error: Server http://www.myopenid.com/server responds that the 'check_authentication' call is not valid What could that be from, it's not a very descriptive error... Does it have to do with something ruby-specific, or is this entirely on the OpenID protocol side of things? More specifically, I am using Authlogic and ActiveRecord, so could this be a problem with my User or UserSession models somehow? Or is it more to do with the header or request? In ruby response I'm getting (from puts inside ruby-openid) is: #<OpenID::Consumer::FailureResponse:0x25e282c @reference=nil, @endpoint=#<OpenID::OpenIDServiceEndpoint:0x2601984 @local_id="http://viatropos.myopenid.com/", @display_identifier=nil, @type_uris=["http://specs.openid.net/auth/2.0/signon", "http://openid.net/sreg/1.0", "http://openid.net/extensions/sreg/1.1", "http://schemas.openid.net/pape/policies/2007/06/phishing-resistant", "http://openid.net/srv/ax/1.0"], @used_yadis=true, @server_url="http://www.myopenid.com/server", @canonical_id=nil, @claimed_id="http://viatropos.myopenid.com/">, @message="Server http://www.myopenid.com/server responds that the 'check_authentication' call is not valid", @contact=nil> Any tips would be greatly appreciated.

• FancyURLOpener failing since moving to python 3.1.2

  - by Andrew Shepherd

  I had an application that was downloading a .CSV file from a password-protected website then processing it futher. I was using FancyURLOpener, and simply hardcoding the username and password. (Obviously, security is not a high priority in this particular instance). Since downloading Python 3.1.2, this code has stopped working. Does anyone know of the changes that have happened to the implementation? Here is a cut down version of the code: import urllib.request; class TracOpener (urllib.request.FancyURLopener) : def prompt_user_passwd(self, host, realm) : return ('andrew_ee', '_my_unenctryped_password') csvUrl='http://mysite/report/19?format=csv@USER=fred_nukre' opener = TracOpener(); f = opener.open(csvUrl); s = f.read(); f.close(); s; For the sake of completeness, here's the entire call stack: Traceback (most recent call last): File "C:\reporting\download_csv_file.py", line 12, in <module> f = opener.open(csvUrl); File "C:\Program Files\Python31\lib\urllib\request.py", line 1454, in open return getattr(self, name)(url) File "C:\Program Files\Python31\lib\urllib\request.py", line 1628, in open_http return self._open_generic_http(http.client.HTTPConnection, url, data) File "C:\Program Files\Python31\lib\urllib\request.py", line 1624, in _open_generic_http response.status, response.reason, response.msg, data) File "C:\Program Files\Python31\lib\urllib\request.py", line 1640, in http_error result = method(url, fp, errcode, errmsg, headers) File "C:\Program Files\Python31\lib\urllib\request.py", line 1878, in http_error_401 return getattr(self,name)(url, realm) File "C:\Program Files\Python31\lib\urllib\request.py", line 1950, in retry_http_basic_auth return self.open(newurl) File "C:\Program Files\Python31\lib\urllib\request.py", line 1454, in open return getattr(self, name)(url) File "C:\Program Files\Python31\lib\urllib\request.py", line 1628, in open_http return self._open_generic_http(http.client.HTTPConnection, url, data) File "C:\Program Files\Python31\lib\urllib\request.py", line 1590, in _open_generic_http auth = base64.b64encode(user_passwd).strip() File "C:\Program Files\Python31\lib\base64.py", line 56, in b64encode raise TypeError("expected bytes, not %s" % s.__class__.__name__) TypeError: expected bytes, not str

• Easy way to observe user activity - how improve my database structure.

  - by Thomas

  Welcome, I need some advise to improve perfomence my web application. In the begin I had this structure of database: USER -id (Primary Key) -name -password -email .... PROFILE -user Primary Key, Foreign Key (USER) -birthday -region -photoFile ... PAGES -id (Primary Key) -user Foreign Key(USER) -page -date COMMENTS -id (Primary Key) -user Foreign Key(USER) -page Foreign Key(PAGE) -comment -date FAVOURITES_PAGES -id (Primary Key) -user Foreign Key(USER) -favourite_page Foreign Key(PAGE) -date but now one of the most important page of website is observatory, when everyone can observe activity others users. So I need select all pages, comments and favourites pages some users and display it in one list, sorted by date. For better perfomance (I think) I changed my structure to this: table USER and PROFILE without changes ACTIVITY (additional table- have common fields: user,date) -id (Primary Key) -user Foreign Key(USER) -date -page Foreign Key(PAGE) -comment Foreign Key(COMMENTS) -favourite_page Foreign Key(FAVOURITES_PAGES) PAGES -id (Primary Key) -page COMMENTS -id (Primary Key) -page Foreign Key(PAGE) -comment FAVOURITES_PAGES -id (Primary Key) -favourite_page Foreign Key(PAGE) So now it is very easy get sorted records from all tables. But I have no only foreign key to PAGES, COMMENTS and FAVOURITES_PAGES in ACTIVITY table - there is about ten Foreign Key fields and in one record only one have value, others have None: ACTIVITY id user date page comment ... 1 2 2010-02-23 None 1 2 1 2010-02-21 1 None .... It is corect solution. When I display about 40 records in one page (pagination) I must wait about one secound, but database is almost emty (a few users and about 100 records in others tables). It is depends on amount records per page - I have checked it, but why it takes too long time, becouse of relationships? The website is built in Python/Django. Any advices/opinion?

• Google Contacts API - No Redirection

  - by mecablaze

  Hello there, I am currently working on Contact Importer web app (in PHP) so I will be able to grab email address from a user's account on Gmail, Yahoo, etc and use them for my own evil purposes. Just kidding, my web app is very friendly. I thought I would start with Google. I found they have a fantastic little API called Google Contacts API which lets a programmer, like myself, to access a user's contacts. After a couple of hours of struggling and throwing shitty code together, I ran into a few road-blocks. My main question is this: Is there any way that I can have a user provide their username and password for Gmail on my website and have my code retrieve the contacts without that nasty redirection to a Google login page? It's kind of ruins the whole flow of my web app. I've looked into AuthSub, and gotten that to work, but of course the catch is that you have to redirect the user to obtain the access token. It looks like OAuth will have this same catch. The one ray of hope I have is the ClientLogin method of authentication. Again, there is a catch, sometimes Google throws you a CAPTCHA instead of the auth token. Again, the user flow is ruined. I've noticed that our good ol' friends over at Twitter have it working just fine. Does anyone know how they do it? Thanks!

• py2app, pyObjc & macports compilation errors

  - by Neewok

  Hi, I'm currently writing a small python app that embeds cherrypy and django using py2app. It worked well until I tried to include pyobjc in my project, since my app needed a small GUI (which consists of a small icon in the top menu bar + a drop down menu). I can run my python script without any problem (I'm using python 2.6 with macports), but I can't launch the application bundle generated by py2app. A dialog box appears with the following message: ImportError: dlopen(/Users/denis/tlon/standalone/mac/dist/django_cherry.app/Contents/Resources/lib/python2.6/lib-dynload/CoreFoundation/_inlines.so, 2): no suitable image found. Did find: /Users/denis/tlon/standalone/mac/dist/django_cherry.app/Contents/Resources/lib/python2.6/lib-dynload/CoreFoundation/_inlines.so: mach-o, but wrong architecture I did a quick : sudo port -u install py26-pyobjc +universal but for some reason macports tries to build openssl, with which compilation fails each time. It seems the problem is related to zLib - this is what appears in the logs : :info:build ld: warning: in /opt/local/lib/libz.dylib, file is not of required architecture ...And here is the output of file /opt/local/lib/libz.dylib : /opt/local/lib/libz.dylib: Mach-O universal binary with 2 architectures /opt/local/lib/libz.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64 /opt/local/lib/libz.dylib (for architecture i386): Mach-O dynamically linked shared library i386 Nothing looks wrong to me. I'm a bit stuck here. I don't even understand what openssl has to do with pyObjc, but it looks like I can't go anywhere if I don't manage to compile it. Macports really suck sometimes :/ EDIT I manage to fix Macports issue, but not py2app one. If I get it right, py2app try to create a 32-bits app, while Core Foundation files on Snow Leopard are for 64 bits architectures. Damn. Either I build this on Leopard, either I have to find a way to create a 64bit app with py2app, but then Snow Leopard only.

• Selecting a Java framework for large application w/ only ONE user

  - by Bijan

  I am building a large application that will be hosted on an AWS server. I'm trying to select a web framework for assisting me with code organization, template design, and generally presentation aspects. Here are some points of consideration: Require security/login/user authentication. I may add the ability in the future to allow more than just an administrator to access the web app, but it is not a public facing website. AJAX support would be helpful. There are a couple widgets that I don't want to recreate. One is a tree object, where the user can expand/contract items in the list, can create new branches, add/edit objects. This would be better off in some dynamic view rather than all done in ugly html. Generally, this is just to provide the application with a face for control, management, and monitoring. Having an easier time adding buttons, CSS, AJAX widgets are great additions though, but not the primary purpose. I'm considering: Wicket Spring Seam GWT Stripe and the list goes on, as I'm sure you all know. I originally planned on using GWT, but then started to feel that GWT didn't cover my primary needs. I could be wrong about this, but there seems to be a lot of support for GWT AND Wicket/Spring. All of this 'getting lost in java frameworks' got me thinking outside the java realm for a framework that would suit my needs that was a clear option, like: JRuby/Rails Jython/Django Groovy/Grails Guice (just throwing this in there... I don't clearly understand the main purposes of all these frameworks. It doesn't seem like DInjection is something I need for a single purpose application) Thanks as always. This community makes Googling for esoteric programming information an order of magnitude better.

• Maintaining a Python web application: heavier vs lighter framework?

  - by Tiberiu Ana

  Five+ years from now, you are hired to support and extend a data-centric web application written in Python that hasn't been kept up to date. Would you rather prefer it was written in the current version of Django/Pylons at the time, using the available standard components, or kept minimal with something like CherryPy/web.py and a few library dependencies? Heavy framework Advantages: standard approach to application design and structure, as encouraged by framework; less application code to worry about. Disadvantages: requires learning the framework to understand how things work; broken things in old version of framework difficult to fix; upgrading to new version potentially difficult due to changing APIs; finding relevant documentation/help potentially difficult due to changing APIs. Light framework Advantages: most application code is directly "visible"; only needed features are implemented; architecture should be simpler to understand; less need to upgrade external dependencies; easier to upgrade external dependencies. Disadvantages: some reinventing the wheel; non-standard design and structure (with the associated unique issues and bugs). I will update the list with any helpful answers.

• Use Google Calendar UI but showing only filtered events

  - by Edwin

  I have just started using Google Calendar API (using Python client). I'm basically developing a web app for a school with Django. What I'd like to achieve is something like this: To make things simple for now, I have 1 Google account and all events will be created in the calendar under that account (this is the school calendar). The calendar will be made public. When a class is created by a teacher, the class schedule will be automatically added as an event in the Google Calendar. When a student logs in, he can see the school calendar, showing only schedules from the classes that he's registered in. I think I can filter the calendar feeds to show only class schedules that a student is registered in using Google Data API. The problem is, how can I display Google Calendar on my web app using Google Calendar UI to show only those filtered events? I can use Google Calendar UI with the provided embeddable HTML snippet, but I can't control/filter events with that (i.e. all events in the school calendar will be displayed). Or perhaps I'm missing something? I read the Data API guide and the Publishing tool doc but I can't seem to find this information. THanks in advance!

• PerformancePoint dashboard permissions problem in MOSS

  - by Nathan DeWitt

  I have a PerformancePoint dashboard running in MOSS 2007 portal. The dashboard consists of one SSRS 2005 report, running in SharePoint Integrated mode. NT Authority\Authenticated Users have read permissions to the report library containing the SSRS report, the dashboard, and the report library containing the dashboard. Users that attempt to access the dashboard receive the following error message: The permissions granted to user 'DOMAIN\firstname.lastname' are insufficient for performing this operation. (rsAccessDenied) Users that then click on the direct link to the report in MOSS will see the report with no problem. Subsequent visits to the dashboard show the report with no problem. The report is using a data source that is located one folder up from the report location. The report has been updated to point to the correct shared data source after deployment. Both the report and the data source have been published. The data source is using stored credentials, with a domain service account that has been set to Use as Windows credentials. This service account is serving other reports in other areas with no problem. Edit: Ok, I've gotten a lot more information on this problem. The request is never actually being made to the data source. The user comes in to the dashboard and requests a report for the first time using their kerberos token identifying themselves. The report looks in the Report Server database and finds that they are not listed in the users table and generates this rsAccessDenied error. Once they view the report directly their name is in this table and they never have the problem again. Unfortunately, removing the user from the Users table in the RS database doesn't actually cause this error to happen again. Everything I've read says that when you run a Report Server in MOSS integrated mode all your permissions are handled at the MOSS report library level, and all Auth users have permissions to the report library, as stated earlier. Any ideas?

  - by lotharsmash

  Hi, I'm trying to use FireWatir (1.6.5) to access a site using Basic Authentication and I've been unable to find a solution that works on Firefox in Linux. Does FireWatir 1.6.5 support Basic Authentication on Linux? I've been searching the web for 2 days and can't get a straight answer anywhere as to how to do this. The only thread I found that seemed helpful was this one ( http://groups.google.com/group/watir-general/browse_thread/thread/d8ab9a177d282ce4/fc1bf2319fb387d8?lnk=gst&q=basic+authentication#fc1bf2319fb387d8). Aedorn Varanis says " Angrez's fork had the solution so I'm using that now. Thanks Angrez, works perfectly!", but he doesn't mention what he did to get things working. Initially I tried to bypass the authentication dialog box by using: browser.goto('http://admin:[email protected]') However, this generates a "Confirm" dialog which says: "You are about to log in to the site "172.20.1.1" with the username "admin"." [Cancel, OK] This dialog blocks, and the goto call won't return until I click "OK". Then I tried adding: browser.startClicker("ok") browser.goto('http://admin:[email protected]') But this ALSO generates the same "Confirm" dialog. I tested out the startClicker functionality using the unit test /var/ lib/gems/1.8/gems/firewatir-1.6.5/unittests/html/JavascriptClick.html and it worked fine, which makes me think that using the startClicker method is NOT the correct way to take care of the Confirm dialog. Anybody else found a way to get Basic Auth to work, or how to click the OK on the confirm dialog? I'm at my wits end...

• IRC Server configuration possibilities

  - by Katai

  I need to know a couple of things, concerning IRC servers that I couldnt directly find out over google (or werent clear enough for me to be sure if it actually works) I'm working at a larger community site, and wanted to deliver an in-page chat. Since it would be a nice feature to let people access it from outside too, over their own clients, I tought implementing an IRC Server would be the best solution (probably dedicated, I'll have to teach myself a couple of things for that) I plan to include a Web-based IRC client over an APE Client / Server. The problem is, I want to strip down the user rights, to disallow many functionalities that IRC would offer: Change of nicknames: The user logs in over the Page login, and I'll automatically create an IRC auth for this user with that password. So basically, he would connect to the IRC client over a button. And after connecting, he shouldnt be able to change his nickname at all Creating channels: I want the possibility to create channels, but not from 'normal' users. Basically, I would prefer to set up basic channels that are public, and if a user really creates an own channel, that one should be private and via invitation (is that possible?) Private conversations: private conversations should be filtered out from the allaround IRC client, into separate 'in-browser-windows' that I create over JS. I guess I just have to filter the stuff coming from IRC - or is there a better solution to that? Only 'registered' users have access: Like I said, if someone registers on the page, I would like to create an IRC 'account' for him. Users that arent registered on the page, cant access the IRC server at all (or get thrown out). Mainly to avoid spammers or bots from outside. Is this stuff solvable over IRC? I've read some FAQ's and Instructions for IRC OP's and servers, but I couldnt find a clear answer - it seems that everyone can do pretty much everything - I would like to configure it in a way that user possibilities are more cut down. Basically, giving users the possibility to chat, but not more. So the Question basically is, how possible / solvable this issues are allaround, or if I have to find other solutions for this.

• PHP/MySQL Printing Duplicate Labels

  - by Michael

  Using an addon of FPDF, I am printing labels using PHP/MySQL (http://www.fpdf.de/downloads/addons/29/). I'd like to be able to have the user select how many labels to print. For example, if the query puts out 10 records and the user wants to print 3 labels for each record, it prints them all in one set. 1,1,1,2,2,2,3,3,3...etc. Any ideas? <?php require_once('auth.php'); require_once('../config.php'); require_once('../connect.php'); require('pdf/PDF_Label.php'); $sql="SELECT $tbl_members.lastname, $tbl_members.firstname, $tbl_members.username, $tbl_items.username, $tbl_items.itemname FROM $tbl_members, $tbl_items WHERE $tbl_members.username = $tbl_items.username"; $result=mysql_query($sql); if(mysql_num_rows($result) == 0){ echo "Your search criteria does not return any results, please try again."; exit(); } $pdf = new PDF_Label("5160"); $pdf->AddPage(); // Print labels while($rows=mysql_fetch_array($result)){ $name = $rows['lastname'].', '.$rows['firstname'; $item= $rows['itemname']; $text = sprintf(" * %s *\n %s\n", $name, $item); $pdf->Add_Label($text); } $pdf->Output('labels.pdf', 'D'); ?>

• Check for modification failure in content Integration using VisualSVN Server and Cruisecontrol.net

  - by harun123

  I am using CruiseControl.net for continous integration. I've created a repository for my project using VisualSvn server (uses Windows Authentication). Both the servers are hosted in the same system (Os-Microsoft Windows Server 2003 sp2). When i force build the project using CruiseControl.net "Failed task(s): Svn: CheckForModifications" is shown as the message. When i checked the build report, it says as follows: BUILD EXCEPTION Error Message: ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: svn: OPTIONS of 'https://sp-ci.sbsnetwork.local:8443/svn/IntranetPortal/Source': **Server certificate verification failed: issuer is not trusted** (https://sp-ci.sbsnetwork.local:8443).

• pylons on production server fedora 8

  - by stormdrain

  I'm interested in learning some python, and thought Pylons would be a good starting point (after spending 2 days trying to get django working -- to no avail). I have an Amazon EC2 instance with Fedora 8 on it. It is a bare-bones install. I am halfway through my second day of trying to get it to work. I have mod_wsgi installed. I have Apache (though that's a later task to tackle). I have easy_install, paster is working fine; basically all of the pre-requisites mentioned throughout the Pylons docs. I can't for the life of me get the thing to work. And I can't seem to find a coherent walkthough anywhere that lists all the steps necessary. There is tons of info out there, but it is all scattered. Wsgi this, python that. Google, google, google... "47 million results found for 'socket.error:(lol, 'Yous a goofs')". So, this is my latest attempt: apachectl -k stop cd /home/ paster create -t pylons test [blah blah.. ok] cd test nano development.ini [hmm, last time I changed the host from 127.0.0.1 to my domain name or url, it threw an error like socket.error: (99, 'Cannot assign requested address')... I'll just leave it] [open port 5000 on firewall] paster serve development.ini [firefox-url:5000] Firefox can't establish a connection to the server Doing these steps locally works as expected. This is just a test to see if I can get it to work at all, which I can't. If I get it to work, then is the task of getting it to work with apache. My madness is that I'd like to play around a little developing and deploying before diving into a full-fledged project. So far: self, I am dissapoint.

• LinkedIn API returning extra/incorrect login prompt

  - by Paul Osetinsky

  I have a Rails application running the omniauth-linkedin gem and linkedin gem (essentialy an API wrapper). When a user logs in, they receive a primary login prompt that displays to them the correct scopes (FULL PROFILE and EMAIL ADDRESS), as below: However, after they log in, they get another login prompt that should not come up, and that ignores the initial scope request. It tells them that LinkedIN is only requesting their PROFILE OVERVIEW, which is incorrect: The problem must lie in my auth_controller, and I think it has do to with the url that is created in one of the authentication stages (definitely right after the user enters their LinkedIn authentication credentials). Here is my auth_controller: require 'linkedin' class AuthController < ApplicationController def auth client = LinkedIn::Client.new(ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET']) request_token = client.request_token(:oauth_callback => "http://#{request.host_with_port}/callback") session[:rtoken] = request_token.token session[:rsecret] = request_token.secret redirect_to client.request_token.authorize_url end def callback client = LinkedIn::Client.new(ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET']) if session[:atoken].nil? pin = params[:oauth_verifier] atoken, asecret = client.authorize_from_request(session[:rtoken], session[:rsecret], pin) session[:atoken] = atoken session[:asecret] = asecret @user = current_user @user.uid = client.profile(:fields => ["id"]).id flash.now[:success] = 'Signed in with LinkedIn.' else client.authorize_from_access(session[:atoken], session[:asecret]) @user.uid = client.profile(:fields => ["id"]).id flash.now[:success] = 'Signed in with LinkedIn.' end @user = current_user @user.save redirect_to current_user end end Just in case, here is my omniauth.rb file that states the scopes I am requesting for my application: Rails.application.config.middleware.use OmniAuth::Builder do provider :linkedin, ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET'], :scope => 'r_fullprofile r_emailaddress', :fields => ['id', 'email-address', 'first-name', 'last-name', 'headline', 'industry', 'picture-url', 'public-profile-url', 'location', 'positions', 'educations'] end Can't figure out how to get rid of that second unnecessary and misleading prompt from LinkedIn and would appreciate any guidance! Thank you.
