Login issue using authentication mode="Forms"

Posted By:      Posted Date: September 15, 2010    Points: 0   Category :ASP.Net
 
Hi,I am using authentication mode="Forms" with ldap, i manage to login and logour fine but when user 1 is logged and when user2 logs, user1 gets the user2 session. Any idea why this might be happening? Here is some code:     <authentication mode="Forms">            <forms name="login" loginUrl="Login.aspx" />        </authentication>        <authorization>            <allow roles="auditor"/>            <allow roles="approver"/>            <allow roles="user"/>            <deny users="?"/>        </authorization>        <identity impersonate="true"/>protected Boolean ValidateUser(String strUsername, String strPassword)        {            //Return true if the username and password is valid, false if it isn't             &n

Cannot Login with Forms Based Authentication to SharePoint 2010 - Issue with the SecurityTokenServic

  
Please be advised I have followed the steps on http://donalconlon.wordpress.com/2010/02/23/configuring-forms-base-authentication-for-sharepoint-2010-using-iis7/. I have tried to fix the following issue for a week using different farms and SharePoint 2010 installations, however I am getting the following error when trying to authenticate using Forms Based into a Claims site: Cannot get Membership Provider with name FBARoleProvider The membership provider for this process was not properly configured. You must configure the membership provider in the .config file for every SharePoint process. 1. I am certain the membership provider is configured in the SecurityTokenServiceApplication webservice as I can manage users and roles in IIS7 using the SecurityTokenServiceApplication website. 2. I am certain that membership provider is configured in the both the Claims Web Application and Central Admin as I can manage users and roles in IIS7 using their websites. 3. I know the issue is the SecurityTokenServiceApplication service as I had to set <serviceDebug includeExceptionDetailInFaults="true" /> to get the error above. 4. I can log into the Claims Based Application using windows authentication, however I am unable to see the users on the people picker despite that I can see them from the application's site on IIS

Forms based users being prompted for windows authentication login for My Sites photos in user lists

  
Here's an issue I didn't see coming for our forms based authentication users. 

We have a web application extended to an external url to handle forms based authentication for users outside of our domain. Our setup looks like this...

Internal Users/Windows Authentication - moss.domain.com
External Users/Forms Based - mossext.domain.com
My Site for Internal Users - mysites.domain.com

When our forms based users are accessing user lists, or discussion pages that display user pictures, they are getting a windows authentication login for our internal users (mysites.domain.com) who have populated their my site with personal photo.

How do we fix this? 

Issue with Forms Authentication

  

 I'm in the middle of converting an intranet application to use forms authentication. The authentication process works fine for the core application and all the nested classic asp pages. However, my nested asp.net applications do not work. I have mapped their web.configs to the correct login url. If I attempt to access them after logging in, I am automatically redirected to the homepage of the intranet application. If I try to access them directly, I am redirected to the login screen, as I should be, and then the intranet homepage after the login process, instead of the page I need to access.

At first, I thought there might be some remnant of the security processes in the nested applications, but it does it for applications that have no security processes other than the one for the core intranet.

Since this is my first crack at using forms authentication, I'm assuming I've missed some step. Any ideas?

Here is the section of my web.config:

<authentication mode="Forms">

      <forms loginUrl="~/folder/loginpage.aspx" name="Cookie Name"></forms>

</authentication>

<authorization>
      <deny users="?" />
      <allow users="*"/>

Windows authentication login form issue

I need to replace the server ip with  XXXX instance name instead of doing this manually.

Could anyone pleas help me out with this one?

Thanks in advance,

 


Forms Authentication shared between 2 Applications, but still getting directed to login page

  
my scenario is: Single Sign-on Within a Sub Domain (two virtual directories under the same sub domain)I've setup both sites using the same forms authentication info in my web.config. both sites have the same machine key's as well. I sign into site1. i click a link that directs to site2. site2 still redirects me to the login page, however on the login page I test HttpContext.Current.User.Identity.IsAuthenticated and it returns true. I also tested on site2's login page to pull the ticket's information and it's pulling everything. so it looks like SSO is working as far as sharing the authentication ticket, yet I cannot figure out why it still puts me on the login page? site 1: https://mysub.mydomain.com/site1/ link in site1 that directs to site2: site 1: https://mysub.mydomain.com/site2/mypage.aspx any ideas? appreciate any help someone could give.

Forms Based Authentication - problem with custom master page and login page

  

Hi,

I have successfully enabled and set up FBA (Forms Based Authentication) on my SharePoint 2010 Foundation server. The thing is that I need to customize the look and feel of the login page. I have successfully customized the page (and master page) to look the way I want, however, when I try to log in, I get the following error/message on the page:
"Forms Based Authentication on classic Web applications has been deprecated".

What I've done:
Made copies of /_layouts/simple.master and /_layouts/login.aspx and renamed the copies. The markup in the master page is MUCH simpler than the original, but I've kept all the ContentPlaceholders that I don't use (most of them) in a hidden <asp:Panel at the bottom of the page.

I've changed the web.config file:
<authentication mode="Forms">
      <forms loginUrl="/_layouts/loginCustom.aspx" />
</authentication>

So, I'm not getting any errors on the page until I try to log in. When I use the default settings (login.aspx and simple.master) it works just fine (but damn that page looks ugly!).

Does anyone know what I might be missing?

Update: I believe the reason it doesn't work is because my custom login aspx is not part of the Claims Based Web Application (because it's sitting

asp.net forms authentication with route handling - error, routes not recognized, returns to login

  


 I just created a small site with form authentication with route handling.  Without forms authentication, the pages route just fine.  With forms, it returns back to the login page as it is not one of my allowed locations specified in my web.config file.

 

I know I probably need to write a custom route handler.  Does anyone have an example I can follow for this?  Thanks.


Sql Server 2008 logs Authentication mode incorrectly avoids remote login

  

Im trying to connect SQL server 2008 Express R2 installed on XP sp3 pc through ODBC SQL Server driver with a Windows 7 PC. I managed to define static IP ports and setup firewall. Now the ODBC connection successfully gets created by accepting uid : sa and my password given.

Now Im getting "login failed for user ". " msg from my application. When I run the same application with same ODBC connection created in the SQL server PC it works fine. The two pcs operate in a workgroup.

Following  is the error log. Im surprised to note that the server logs its in Mixed mode initially and later makes a cry that its in Windows Authentication mode. !!!!

ASP.NET Forms Authentication Issue - IE8

  

Hi,

I've recently noticed a problem that prevents users from logging into my website when running IE8 on Vista.  I think it is a security issue that prevents the authentication cookie from working.  There seems to be an issue with either of these two methods:

FormsAuthentication.SetAuthCookie
FormsAuthentication.RedirectFromLoginPage

Authentication works ok in FireFox and Google Chrome running on the same Windows Vista machine with the IE8 problem.  Authentication works ok on a 2003 server computer running IE7.  I'm pretty sure authentication was working previously in IE8 - maybe the issue is related to a recent hotfix?

I managed to get authentication to work in IE8 by adding my website to the "trusted sites" zone.  Also, it worked ok when I disabled "Protected Mode". 

Has anybody else had this problem?  Also, is there a way to get this working without forcing people to make changes to their IE security settings?

 Many Thanks,

 David 

 


login pages without using Forms authentication

  

Hi,

I want to create a website that a user can logon and view their data. They should also be able to logout. I'm wondering how to achieve this WITHOUT using the Membership provider api provided by Microsoft. This is what I think should happen , please advise me if I'm incorrect.

1. user enters name and password and clicks button.

2.If username and password are correct the user is redirected to a webpage with their details.

3.A session is created.

4.The user logouts and the session is deleted.


Is this the way to go about it? If anyone has some similar code that I could reference that would be great

Login problem with MySQL forms authentication

  

I can login in locally using the development server, but after uploading the files- including MySql.Data.dll and MySql.Web.dll - to my hosting server I can't. There is no errors, it just won't login. I can get records from my database, so I know it's not the connection.

Explained: Forms Authentication in ASP.NET

  
This module explains how forms authentication works in ASP.NET version 2.0. It explains how IIS and ASP.NET authentication work together, and it explains the role and operation of the FormsAuthenticationModule class.

Using Forms Authentication in ASP.NET - Part 1

  
Classic ASP developers often had to "roll their own" authentication scheme, however, in ASP.NET much of the grunt work has been taken out. This article outlines how things have changed and how FormsAuthentication can be used to secure a Web site with a minimal amount of code.

ASP.NET Forms Authentication - Part 1

  
Often, in legacy Web applications, users authenticate themselves via a Web form. This Web form submits the user's credentials to business logic that determines their authorization level. Upon successful authentication, the application then submits a ticket in the form of a cookie, albeit a hard cookie or session variable. This ticket contains anything from just a valid session identification access token to customized personalization values.
