I have setup windows and forms based authentication on one of my web applications and have an issue while trying to sign in as fbaadmin. fbaadmin is one of the users I have added to the FBADB on SQL2008 through .NET users from IIS. I have no issue signing in using windows authentication but am unable to use the FBA user. I am also unable to even bring up the sign in page outside of the server. I get the same error screen in both cases. Here is a screenshot for reference. Please advise. Thanks FBA Sign in error

Have you made the required changes to the web.config files in each of the following locations?

  1. SharePoint Central Administration
  2. Security Token Service ([SharePoint root]\WebServices\SecurityToken)
  3. Your web application

Should you wish to modify the web.config files by hand (do so carefully!), the instructions can be found in step III of this walk-through.

Alternately, you can make these same changes through the IIS admin interface. Detailed procedures for doing that can be found here.

I recall receiving similar errors to the ones you are seeing when I first set up FBA in SharePoint 2010 and did not correctly modify the STS web.config. Failing that, you can also set includeExceptionDetailInFaults="True" in the <serviceDebug> element of your STS web.config to get additional error information, as suggested in the screenshot from Event Viewer you posted above.
