• Failed to generate a user instance of SQL Server

  - by Goondocks

  I'm using Windows 7 Beta and trying to install a web application locally. This web site uses Microsoft SQL Server 2005 Express (SQLEXPRESS) and a MDB file in the web site's ~/App_Data folder. I was instructed to configure IIS7 to use Classic .NET AppPool for this web application. Each time the web site loads, I receive the following error: There was an error trying to connect to the Database Server: Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed. The Internet is packed with articles written on this subject. The prevailing wisdom seems to be: Configure the SQL Express Service to use the Local System account. Delete the following directory: C:\Users\username\AppData\Microsoft\Microsoft SQL Server Data\SQLEXPRESS Neither of these fixes have made any impact. I have tinkered with permissions and settings for hours to no avail. Can anyone suggest a fix or help me understand how to get more detailed information about the problem.

• How to create public html (apache2) with LDAP authentication?

  - by borjamf

  Im running Apache2 on Ubuntu 12.04 Server because I want to create a home directory for each ldap user. I'm using LDAP for authentication and it's working ok. Also I've done some tests with LDAP module for Apache2 and it's working ok. The problem with this LDAP authentication is that any success login can access to ~user/public_html, even if the user is not the owner of that home. I dont know how to control that, for example, userldap2 access to userldap1/public_html. I want that only the userldap1 access to userldap1. Could anybody tell me how to control that with LDAP authentication? I hope that you'll understand me. My config (auth_ldap.conf) <Directory /home/disco2/*/public_html> AuthName "Authentication" AuthType basic AuthBasicProvider ldap AuthzLDAPAuthoritative off AuthLDAPURL ldap://prueba.borja/dc=prueba,dc=borja?uid? Require ldap-filter objectClass=posixAccount </Directory>

• Fixing a typo in machine name

  - by justSteve

  When i installed windows i had a typo in the machine name that i corrected from the system's 'Computer Name/Domain Changes' - the workstation is a member of a workgroup not a domain. From everything i can see the renamed machine name is correct. Shift gears.... I'm importing SQL logins from my remote server to this, my development workstation and have used the script presented here - a script that generates a CREATE statement for each login found. While I was preparing to run this script's output (from the remote box) i needed to change the domain name from the remote to my local's name - so i ran the same script locally (in order to see what SQL things my domain name is. SQL has the original machine name - the one with the typo. However, the scripts are tossing errors if i try to create logins with that identifier. CREATE LOGIN [Setve\Admin] FROM WINDOWS WITH DEFAULT_DATABASE = [master] But works correctly if i use the updated machine name: CREATE LOGIN [Steve\Admin] FROM WINDOWS WITH DEFAULT_DATABASE = [master] So the problem is: do i have a problem i need to solve? Somewhere, deep in the guts of SQL Server, it has record of a Domain name that does not exist. Should i find and fix that discrepancy? thx

• How to start MSSQL Server with corrupt model db

  - by Jordan McGuigan

  After moving some databases around (restoring, deleting, etc) we experienced an issue creating new databases. Specifically, When trying to create a new database MSSQL Server it failed because the "The database 'model' is marked RESTORING and is in a state that does not allow recovery to be run". As some online solutions suggested, we tried to Start and Stop the MSSQL Service. Service would not restart because "Could not create tempdb. You may not have enough disk space available. Free additional disk space by deleting other files on the tempdb drive" (FYI: the drive has 100gb of free space). Tried restarting the machine the MSSQL Server is running on. When the server came back online, we received the same error. We have tried deleting tempdb.mdf and restoring the modeldb from the templates folder, but neither of these solved the issue. We are unable to connect to the database, even in single user mode. Many of the online solutions have us running SQL commands against the server, but we are unable to connect (even in single user mode) to the DB to run commands against the server. Specific error messages: Database 'model' cannot be opened. It is in the middle of a restore. (Microsoft SQL Server, Error: 927) The SQL Server (MSSQLSERVER) service is starting. The SQL Server (MSSQLSERVER) service could not be started. A service specific error occurred: 1814. We need the server up and running again ASAP.

• Server periodically freezing - Help Stabilizing

  - by JonDog

  We run an asp.net/sql server data collection website with a hand full of clients dumping data in and running reports. We moved to a new server (specs below) and have had issues with it freezing and having to reboot it a dozen times over the pass six months. The hosting company has mentioned possible causes (listed below) but cant give a definite answer on what is going wrong. They have offered to reconfigure how ever I like. We have benefited from having a much faster system and really dont want to get rid of the ssd's unless they are the issue. Two possible setup changes that I've talked with them about are also listed below. Any suggestions on what maybe causing the freezing issue as well as suggestion on a new setup would be great. My main questions are: Do SSD generally have problems running the OS & SQL Server on the same RAID Array? and Are the new SSD's still unrefined enough to be running in a production environment?

• How to use SharpSVN in ASP.NET?

  - by Bryan

  Trying to use use SharpSVN in an ASP.NET app. So far, it's been nothing but trouble. First, I kept getting permission errors on "lock" files (that don't exist), even though NETWORK SERVICE has full permissions on the directories. Finally in frustration I just granted Everyone full control. Now I get a new error: OPTIONS of 'https://server/svn/repo': authorization failed: Could not authenticate to server: rejected Basic challenge (https://server) This happens whether I have the DefaultCredentials set below or not: using (SvnClient client = new SvnClient()) { //client.Authentication.DefaultCredentials = new System.Net.NetworkCredential("user", "password"); client.LoadConfiguration(@"C:\users\myuser\AppData\Roaming\Subversion"); SvnUpdateResult result; client.Update(workingdir, out result); } Any clues? I wish there was SOME documentation with this library, as it seems so useful.

• ASP.NET MVC: AuthorizeAttribute on default page

  - by AlexB

  The default controller in my ASP.NET MVC project is decorated with the [Authorize] attribute. When I deploy the website on my development machine and access the website, I am redirected to the login page (defined in forms loginUrl section of the Web.Config). Result: everything works as expected. When I publish the website on our production server (Windows Server 2008, IIS 7, DefaultAppPool) and access the website, the expected address shows in the address bar (/Account/LogOn?ReturnUrl=*my_expected_return_url*), but the page displays "You do not have permission to view this directory or page." instead of the login page. If I remove the [Authorize] attribute on the default controller/action, the page displays correctly. My Web.Config file: sessionState mode="InProc" timeout="30" authentication mode="Forms" forms loginUrl="~/Account/LogOn" timeout="2880"

• RedirectFromLogin in Silverlight Login Page

  - by Oliver

  I am busy writing a login page in Silverlight. I am using an Authentication Service that processes the logins and I am also creating a custom Membership and Roles providers. Everything is working but I need some assistance. I would like some advice on how to redirect the user to page they came from before they were pushed to the Login page. Basically I want the same behavior as the standard ASP.Net login. I am fully aware of the differences between ASP and Silverlight regarding Client and Server side models. I can do the navigation but I always lose the session and cookie when I perform HtmlPage.Window.Navigate() to the ReturnUrl...

• WCF via Windows Service - Authenticating Clients

  - by Sean

  I am a WCF / Security Newb. I have created a WCF service which is hosted via a windows service. The WCF service grabs data from a 3rd party data source that is secured via windows authentication. I need to either: Pass the client's privileges through the windows service, through the WCF service and into the 3rd party data source, or... Limit who can call the windows service / WCF service to members of a particular AD group. Any suggestions on how I can do either of these tasks?

• Storing user info in Session using an Object vs. normal variables

  - by justinl

  I'm in the process of implementing a user authentication system for my website. I'm using an open source library that maintains user information by creating a User object and storing that object inside my php SESSION variable. Is this the best way to store and access that information? I find it a bit of a hassle to access the user variables because I have to create an object to access them first: $userObj = $_SESSION['userObject']; $userObj->userId; instead of just accessing the user id like this how I would usually store the user ID: $_SESSION['userId']; Is there an advantage to storing a bunch of user data as an object instead of just storing them as individual SESSION variables? ps - The library also seems to store a handful of variables inside the user object (id, username, date joined, email, last user db query) but I really don't care to have all that information stored in my session. I only really want to keep the user id and username.

• Rails application settings?

  - by Danny McClelland

  Hi Everyone, I am working on a Rails application that has user authentication which provides an administrators account. Within the administrators account I have made a page for sitewide settings. I was wondering what the norm is for creating these settings. Say for example I would like one of the settings to be to change the name of the application name, or change a colour of the header. What I am looking for is for someone to explain the basic process/method - not necessarily specific code - although that would be great! Thanks, Danny

• Python urllib2 Basic Auth Problem

  - by Simon

  I'm having a problem sending basic AUTH over urllib2. I took a look at this article, and followed the example. My code: passman = urllib2.HTTPPasswordMgrWithDefaultRealm() passman.add_password(None, "api.foursquare.com", username, password) urllib2.install_opener(urllib2.build_opener(urllib2.HTTPBasicAuthHandler(passman))) req = urllib2.Request("http://api.foursquare.com/v1/user") f = urllib2.urlopen(req) data = f.read() I'm seeing the following on the Wire via wireshark: GET /v1/user HTTP/1.1 Host: api.foursquare.com Connection: close Accept-Encoding: gzip User-Agent: Python-urllib/2.5 You can see the Authorization is not sent, vs. when I send a request via curl: curl -u user:password http://api.foursquare.com/v1/user GET /v1/user HTTP/1.1 Authorization: Basic =SNIP= User-Agent: curl/7.19.4 (universal-apple-darwin10.0) libcurl/7.19.4 OpenSSL/0.9.8k zlib/1.2.3 Host: api.foursquare.com Accept: */* For some reason my code seems to not send the authentication - anyone see what I'm missing? thanks -simon

• How to use Windows login for single-sign-on and for Active Directory entries for Desktop Java applic

  - by Touko

  I'd like to have my desktop Java application to have single sign on related to Active Directory users. In two steps, I'd like to : Be sure that the particular user has logged in to Windows with some user entry. Check out some setup information for that user from the Active Directory With http://stackoverflow.com/questions/31394/java-programatic-way-to-determine-current-windows-user I can get the name of the current Windows user but can I rely to that? I think the System.getProperty("user.name") won't be secure enough? ("user.name" seems to be got from environment variables, so I can't rely on that, I think?) Question http://stackoverflow.com/questions/390150/authenticating-against-active-directory-with-java-on-linux provides me the authentication for given name+pass but I'd like to authenticate based on the Windows logon? For the Active Directory access, the LDAP would probably be the choise? I'm not totally sure if I'm asking the right questions but hopefully somebody has some ideas to forward me on.

• Can django's auth_user.username be varchar(75)?

  - by perrierism

  Django's auth_user.username field is 30 characters. That means you can't have auth_user.username store an email address. If you want to have users authenticate based on their email address it would seem you have to do some wonky stuff like writing your own authentication backend which authenticates based on (email, password) instead of (username, password) and furthermore, figuring out what you're going to put in the username field since it is required and it is a primary key. Do you put a hash in there, do you try to put the id in there... bleh! Why should you have to write all this code and consider edge cases simply because username is too small for your (farily common) purposes? Is there anything wrong with running alter table on auth_user to make username be varchar(75) so it can fit an email? What does that break if anything?

• PHP Session when using desktop app

  - by Jonathan

  In this question I asked how to POST to a php file form a vb.net app: http://stackoverflow.com/questions/2615335/post-to-webpage-in-vb-net-win-forms-desktop-not-asp-net So now I've logged in the user user by posting their username and password to the php file, the php file then does security/checks they exist/etc and if both username and password are correct is stores the user ID in a session variable. Now if the vb.net app tries to download data off a page which needs the user to logged in, it checks this by doing: if (!isset($_SESSION['uid'])) { header("Location: index.php"); } However after having logged correctly in the app the session variable is not set. How does session work with a vb.net app like this? When the user logs in successfully should I download the user id and keep it in the vb.net app and then post it to each page that requires authentication?

It is required to show on the silverlight pages different information for authorised and non-authorised users. Is there any possibility to track on the Silverlight side if user is already authorized on the server side (on the usual ASP.NET web-site)? Please adivse how to do this. Thank you in advance.

• What is a hardware-id?

  - by Rob

  Some forums that I regularly visit sell premium programs, and to prevent them from being leaked they use hardware-id authentication. That is, first they send you a program to run to grab your HWID, you tell them your HWID, they store it in a database, then they send you the actual program. If your HWID isn't in the database, the program won't run. So what is Hardware-ID, and how is it generated? Why is it that my HWID is different depending on the programmer that sends me a HWID-grabber?

• log in as a proxy for a certain user

  - by Samuel

  We have a requirement, wherein the administrative user needs to proxy in as a certain user in an environment where several users (Role: User) are managed by an administrator (Role: Admin). e.g If we have the following users in the database (admin, user1, user2, user3), we would want the admin to proxy as 'user2' and use the system in certain scenarios. Authentication in our web application is based username / password credentials, what mechanisms are available for the admin to proxy as 'user2' when he doesn't have the password for 'user2'. How can the application track such access for audit purposes to mention that 'admin' had proxied for 'user2' and performed certain actions. I am looking for suggestions on supporting this in our j2ee (jboss seam) web application.

I was thinking of creating a TT template that dose that, but was wondering if their is a tool that do that. Any ideas or thoughts. The only tables that i would keep in SQL Azure would anything related to transactions like payments. Appreciate your thoughts and advice

• Backup Google Calendar programmatically: http://www.google.com/reader/subscriptions/export

  - by Michael

  I'm struggling with writing a python script that automatically grabs the zip fail containing all my google calendars and stores it (as a backup) on my harddisk. I'm using ClientLogin to get an authentication token (and successfully can obtain the token). Unfortunately, i'm unable to retrieve the file at https://www.google.com/calendar/exporticalzip It always asks me for the login credentials again by returning a login page as html (instead of the zip). Here's the critical code: post_data = post_data = urllib.urlencode({ 'auth': token, 'continue': zip_url}) request = urllib2.Request('https://www.google.com/calendar', post_data, header) try: f = urllib2.urlopen(request) result = f.read() except: print "Error" Anyone any ideas or done that before? Or an alternative idea how to backup all my calendars (automatically!)

• Connecting to SQL Server with Visual Studio Express Editions

  - by tlianza

  I find it odd that in Visual C# 2008 Express edition, when you use the database explorer, your options are: 1) Microsoft Access 2) SQL Server Compact 3.5, and 3) SQL Server Database File. BUT if you use Visual Web Developer 2008 Express, you can connect to a regular SQL Server, Oracle, ODBC, etc. For people developing command-line or other C# apps that need to talk to a SQL Server database, do you really need to build your LINQ/Data Access code with one IDE (Visual Web Developer) and your program in another (Visual C#)? It's not a hard workaround, but it seems weird. If Microsoft wanted to force you to upgrade to Visual Studio to connect to SQL Server, why would they include that feature in one of their free IDEs but not the other? I feel like I might be missing something (like how to do it all in Visual C#). Thanks! Tom

• best way to authenticate and consume web service using phonegap (html5/javascript)

  - by Raiss

  I am going to develop a phonegap application which is pretty simple. I need to implement an authentication and some simple data transfer back and forth to the phone and server. I prefer to use ASP.NET as a web service and our database is MS SQL but I am not sure what approach should I take to create a secure communication between Phonegap App and webservice. The problem with a simple AJAX request is limitation in cross-domain and I’m not sure if JSONP is a good option. I was wondering if someone can tell me what technology I should use in order to make a semi secure connection which works with PhoneGap (html5, javascript ) and .Net webservice. I understand that it’s a general question but I need to know what technology is the best in such a case. thanks

• What one-time-password devices are compatible with mod_authn_otp?

  - by netvope

  mod_authn_otp is an Apache web server module for two-factor authentication using one-time passwords (OTP) generated via the HOTP/OATH algorithm defined in RFC 4226. The developer's has listed only one compatible device (the Authenex's A-Key 3600) on their website. If a device is fully compliant with the standard, and it allows you to recover the token ID, it should work. However, without testing, it's hard to tell whether a device is fully compliant. Have you ever tried other devices (software or hardware) with mod_authn_otp (or other open source server-side OTP program)? If yes, please share your experience :)
