• ASP.NET authentication login and logout with browser back button

  - by Eatdoku

  Hi, I am looking for a solution for user use the browser's back button to navigate to previous page once logged out. I have a web application build in asp.net and using a custom membership provider for authentication and authorization. Everything works fine except when the user click on the logout link to log out of the application and being redirect to a default cover page, if the use click on the BACK BUTTON on their browser, it will actually go back to where they were before and the data will still show up. Of course they can't do anything on that page, click on anything link they will be redirect to a login page again. But having those information display is making a lot users confused. i am just wondering if there is any way i can either clear the browser's history so use can't go BACK, or when they click on the back button and have them redirect to the login page. thanks

• jQuery ajax in DotNetNuke preserving user authentication

  - by Michael Bradley

  I want to use jQuery's ajax functionality in a DotNetNuke module I'm developing. I want the ajax call to be authenticated via DNN's membership functionality. I want the ajax response as json. How can I do this? I've looked at IWeb and IWebCF -- it's not clear to me from much Googleing and scanning the forums whether these modules would allow me to create a web service that would accept a simple post request and return json (seems like they want to do it the ASP.NET AJAX way with a generated proxy, I'd prefer to just use jQuery's AJAX call functionality). Seems you can't create a simple webmethod in a DNN module (since they are developed as User Controls (.ascx)). I could deploy an .asmx file with module, but that won't leverage DNN's authentication system. Ideas? I'm currently developing against DNN 4.9.5

• Windows Authentication for winforms with Windows 2000

  - by The King

  I use the following code to validate users through windows authentication for my winform application. This works fine with windows XP but when the user is using windows 2000, it says that the userid or password is in valid. How do I do this in Windows 2000. Further, How do I detect whether the user is using Windows Xp or windows 2000. [System.Runtime.InteropServices.DllImport("advapi32.dll")] public static extern bool LogonUser(string userName, string domainName, string password, int LogonType, int LogonProvider, ref IntPtr phToken); public bool IsValidateCredentials(string userName, string password, string domain) { IntPtr tokenHandler = IntPtr.Zero; bool isValid = LogonUser(userName, domain, password, 2, 0, ref tokenHandler); return isValid; } Thanks

• Programmatic authentication in JEE 6

  - by Kevin

  Hello, is it possible to authenticate programmatically a user in J2ee 6? Let me explain with some more details: I've got an existing Java SE project with Servlets and hibernate; where I manage manually all the authentication and access control: class Authenticator { int Id string username } Authenticator login(string username, string password) ; void doListData(Authenticator auth) { if (isLoggedIn(auth)) listData(); else doListError } void doUpdateData (Authenticator auth) { if (isLoggedAsAdmin(auth)) updateData() ; else doListError(); } void doListError () { listError() ; } And Im integrating J2ee/jpa/servlet 3/... (Glassfish 3) in this project. I've seen anotations like : @RolesAllowed ("viewer") void doListdata (...) { istData() ; } @RolesAllowed("admin") void doUpdateData (...) { updateData() ; } @PermotAll void dolisterror () { listerror() ; } but how can I manually state, in login(), that my user is in the admin and/or viewer role?

• Client authentication with RubyLDAP ldap

  - by Marcelo de Moraes Serpa

  Hello all, I'm trying to implement a feature that uses LDAP over SSL (SSL, not TLS), it needs to connect to a SSL-enabled LDAP server (i.e OpenLDAP), bind and then do any additional queries. It also needs to support client-authentication, and this is where things get tricky: The client is a web application written in Ruby, and we are using RubyLDAP (so far we have used it for non-SSL ldap stuff with great success). My question is: Is there a way to load a client certificate and send its data over the wire to the LDAP server when doing a LDAP::SSLConn? I haven't found anything obvious on the API docs (http://ruby-ldap.sourceforge.net/rdoc/) nor while googling around. I know I that I can prevent the server from asking for a certificate by putting the following on slapd.conf (OpenLDAP): TLSVerifyClient never However, this is not an option here. Thanks, Marcelo.

• ASP.NET MVC Authentication Cookie Not Being Retrieved

  - by Jamie Wright

  I am having a hard time implementing "Remember Me" functionality in an MVC application with a custom principal. I have boiled it down to ASP.NET not retrieving the authentication cookie for me. I have included a snaphot below from Google Chrome. Shows the results of Request.Cookies that is set within the controller action and placed in ViewData for the view to read. Notice that it is missing the .ASPXAUTH cookie Shows the results from the Chrome developer tools. You can see that .ASPXAUTH is included here. Does anyone know what the issue may be here? Why does ASP.NET not read this value from the cookie collection?

• SAML Authentication Portal

  - by Alvin Jones

  I'd like to develop a portal similar to what a company like OneLogin (http://www.onelogin.com/) has: The user would login with their login credentials then have links to the web resources that their account is associated with. When they see their resources all they need to do is click on them and they'll be automatically login in (SAML authentication). Are there any open source projects out there that have started on this effort? It would be great if there was something that we could use as a base to build on top of with a friendly license (e.g. MIT). Thanks

Client is XP & server 2003. Why? How do get it to work?

• django authentication .htaccess static

  - by Uszy Wieloryba

  In my app users can upload files for other users. To make the uploaded files accesible only for the addresse I need some kind of static files authentication system. My idea, is to create the apache hosted directory for each user and to limit access to this derectory using .htaccess. This means that each time new django user is created, I need to create a directory and the appropriate .htaccess file in it. I know I should do it using post_save signals on User model but I don't know how to create the .htaccess in the user's directory from python level. Can you help me with that? Or perhaps you have better solution to my problem?

• Separation of concerns and authentication

  - by Tom Gilder

  I'm trying to be a Good Developer and separate my concerns out. I've got an ASP.NET MVC project with all my web code, and a DAL project with all the model code. Sometimes code in the DAL needs to check if the current user is authorized to perform some actions, by checking something like CurrentUser.IsAdmin. For the web site, the current is derived from the Windows username (from HttpContext.Current.User.Identity), but this is clearly a web concern and shouldn't be coupled to the DAL. What's the best pattern to loosely couple the authentication? Should the DAL be asking the MVC code for a username, or the MVC be telling the DAL? Are there advantages or disadvantages to one or the other? Thank you!

• Geolocation under firefox 3.6 requires Proxy Authentication?

  - by prem

  I am trying to share my location on geolocation enabled pages from firefox 3.6, but doesn't seem to get any kind of success or failures. When I wrote my custom js containing navigator.geolocation.getCurrentPosition(func1,func2), the success callback isn't called at all. When I tamper the http requests on firefox, the request to https://www.google.com/loc/json returns with status: 407 [Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )]... Yes, my network is behind a proxy server. But the same works with Chrome. I didn't try other browsers yet.

• http_post_data basic authentication?

  - by kristian nissen

  I have a remote service that I need to access, according to the documentation it's restricted using basic authentication and all requests have to be posted (HTTP POST). The documentation contains this code example - VB script: Private Function SendRequest(ByVal Url, ByVal Username, ByVal Password, ByVal Request) Dim XmlHttp Set XmlHttp = CreateObject("MSXML2.XmlHttp") XmlHttp.Open "POST", Url, False, Username, Password XmlHttp.SetRequestHeader "Content-Type", "text/xml" XmlHttp.Send Request Set SendRequest = XmlHttp End Function how can I accomplish this in PHP? When I post data to the remote server it replies: 401 Unauthorized Access which is fine because I'm not posting my user/pass just the data. Bu when I add my user/pass as it's describe here: http://dk.php.net/manual/en/http.request.options.php like this: $res = http_post_data('https://example.com', $data, array( 'Content-Type: "text/xml"', 'httpauth' => base64_encode('user:pass'), 'httpauthtype' => HTTP_AUTH_BASIC ) ); the protocol is https - I get a runtime error in return (it's a .Net service). I have tried it without the base64_encode but with the same result.

• Teamcity NTLM Authentication change - admin user lost in transition

  - by hawkeye

  I've switched in teamcity from using basic authentication to using NTLM, on an existing installation. This works fine, except that the admin user didn't have a corresponding NT account, and so doesn't work on the NTLM configuration. (It is easy to roll back, so it is not a stress). My question is - what is the command to set a user to admin manually - ie modifying the database? (like this: TeamCity forgotten admin password - where to look?) but changing the role of a user to global system administrator.

• authentication in PHP ?

  - by user296516

  Hi guys, I need to make an authentication script in php. I have already made a login.php page, where the user can enter his unsername/password and it gets checked against a database. If the unsername/password are correct, the user should be forwarded to members.php page together with a $_SERVER['username'] variable. What is the command in PHP to go to another webpage, in this case members.php ? in pseudocode I see it like this: if ( unsername/password are OK ) { $_SERVER['username'] = $username; goto(members.php); } Thanks!

• Authentication Error in C# Send Mail App

  - by doc

  I'm developing a simple send mail app in C#, using my CMail Server: MailMessage mail = new MailMessage("[email protected]", "[email protected]"); mail.Subject = "Sub"; mail.Body = "Hi!"; SmtpClient smtp = new SmtpClient("MyServer"); System.Net.NetworkCredential cred = new System.Net.NetworkCredential("user", "pass"); smtp.UseDefaultCredentials = false; smtp.Credentials = cred; smtp.Send(mail); Obviously i ommited my account information, so, this code throws me an Authentication Exception for some reason. I first thought that the code was wrong, so i change the info to my gmail account and everything goes fine, with the only SMTP server that i having trouble is with the CMail. Is there a problem with .NET and CMail's SMTP ? Thanks for the help and comments!

• Script SQL Server login with Windows authentication without machine name

  - by Evgeny

  I want to write a SQL 2005 script to create a new login that uses Windows authentication. The Windows user is a local account (not a domain one). A local account with the same name exists on many SQL Server machines and I want to run the same script on all of them. It seemed simple enough: CREATE LOGIN [MyUser] FROM WINDOWS However, that doesn't work! SQL returns an error, saying Give the complete name: <domain\username>. Of course, I can do that for one machine and it works, but the same script will not work on other machines.

• Best way to perform authentication on every request

  - by Nik

  Hello. In my asp.net mvc 2 app, I'm wondering about the best way to implement this: For every incoming request I need to perform custom authorization before allowing the file to be served. (This is based on headers and contents of the querystring. If you're familiar with how Amazon S3 does rest authentication - exactly that). I'd like to do this in the most perfomant way possible, which probably means as light a touch as possible, with IIS doing as much of the actual work as possible. The service will need to handle GET requests, as well as writing new files coming in via POST/PUT requests. The requests are for an abitrary file, so it could be: GET http://storage.foo.com/bla/egg/foo18/something.bin POST http://storage.foo.com/else.txt Right now I've half implemented it using an IHttpHandler which handles all routes (with routes.RouteExistingFiles = true), but not sure if that's the best, or if I should be hooking into the lifecycle somewhere else? Many thanks for any pointers. (IIS7)

• ejabberd - LDAP authentication

  - by Armadillo

  Hi I'm trying to configure an ejabberd installation, using LDAP authentication, but I just can't login, even with the admin user. This is part of my ejabberd.cfg file: %... {auth_method, ldap}. {ldap_servers, ["server2000.tek2000.local"]}. {ldap_port,389}. {ldap_uidattr, "uid"}. {ldap_base, "dc=server2000,dc=tek2000,dc=com"}. {ldap_rootdn, "[email protected]"}. {ldap_password, "secret"}. %... What am I missing? I must say that, with OpenFire, I can connect using this credentials/configuration. I'm using Spark as my client application. Thanks

• double authentication issue on IIS / Report Server (SQL server 2008)

  - by Vinzz

  Hi, On a 2003 server box, with SQL server 2008 installed (ReportServer deployed in IIS mode), I've got a virtual directory within IIS with it's security set to 'windows authentication', with the following html code: <body> <h1>test</h1> <iframe src="/reportserver" witdh="50%" height="50%" /> </body> From the outside, I've got a first login/pwd box displayed to access the html code, then a second one to display the content of the iframe. On the same type of server, but with SQL Server 2005, I don't have this issue (i.e. only one login box). My thought is that the first token should give acces to both the page and the iframe, isn't it? Any hints on how to setup the reportserver to fix this? thanks.

What do you use in Production to authenticate your users? Any help in this will be helpful. Thanks

• The remote server returned an error: (407) Proxy Authentication Required

  - by chris

  I'm getting this error when I call a web service: "The remote server returned an error: (407) Proxy Authentication Required". I get the general idea and I can get the code to work by adding myProxy.Credentials= NetworkCredential("user", "password", "domain"); or by using DefaultCredentials in code. My problem is that the call to the web service works in production without this. It seems like there is a non code solution involving Machine.config, but what is it? At the moment I can't get to the production boxes machine.config file to see what that looks like. I tried updating my machine.config as follows, but I still get the 407 error.

• Books/resources on authentication and authorization in layered applications

  - by Tommy Jakobsen

  I've been trying to find resources and guidelines for implementing authentication and authorization in multiple layered architectures (C#), but haven't found any "best practices" or patterns to use. And I figured, that there must be some patterns for this, as it is a pretty important area? The application that we're developing, is layered traditionally, having data layer (Entity Framework 4) repositories domain layer service layer (can be WCF, with data transfer objects) multiple clients consuming the WCF service (ASP.NET [MVC], Silverlight, WPF) and clients accessing a service layer directly (no WCF) Are there books/articles/blogs that dig deeply into this area? Primarily about authorization such as handling multiple roles and attributes attached to users). It doesn’t have to be specific for the .NET Framework, but it would be preferred.
