This is very annoying error because we do not have exact what is going wrong. To receive that error message that is occurring do the following:

1>     Open IIS (Internet Information Server) and navigate to “SharePoint Web Services”  subsection under “Sites” Section. Click the node open and select “SecurityTokenServiceApplication” , right click and click on “Explore”

2>    You can see web.config file in the windows. Open this file and look for the following section:

<behaviors>

  <serviceBehaviors>

    <behavior name="SecurityTokenServiceBehavior">

      <!-- The serviceMetadata behavior allows one to enable metadata (endpoints, bindings, services) publishing.

           This configuration enables publishing of such data over HTTP GET.

           This does not include metadata about the STS itself such as Claim Types, Keys and other elements to establish a trust.

      -->

      <serviceMetadata httpGetEnabled="true" />

      <!-- Default WCF throttling limits are too low -->

      <serviceThrottling maxConcurrentCalls="65536" maxConcurrentSessions="65536" maxConcurrentInstances="65536" />        

    </behavior>

  </serviceBehaviors>

</behaviors>

Add an extra debug tag in this section. The tag looks like this:

<serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true" />

This tag needs to be placed in the behavior tag. After you place the tag in the section it will look like this:

<behaviors>

  <serviceBehaviors>

    <behavior name="SecurityTokenServiceBehavior">

      <!-- The serviceMetadata behavior allows one to enable metadata (endpoints, bindings, services) publishing.

           This configuration enables publishing of such data over HTTP GET.

           This does not include metadata about the STS itself such as Claim Types, Keys and other elements to establish a trust.

      -->

      <serviceMetadata httpGetEnabled="true" />

      <!-- Default WCF throttling limits are too low -->

      <serviceThrottling maxConcurrentCalls="65536" maxConcurrentSessions="65536" maxConcurrentInstances="65536" />

      <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true" />

    </behavior>

  </serviceBehaviors>

</behaviors>

After changing the “web.config” we received the detailed and correct message

Server Error in '/' Application.

Error was “FormsAuthUser” Password has been changed.

So you have the detail of the error and you have clue what is going on.

Enjoy Debugging!!!
