CRM 2013 ADFS 2.1 SDK Calls, Error: System.NotSupportedException: The authentication endpoint Username was not found on the configured Secure Token Service

Hi Community,

I have successfully configures CRM 2013 with IFD. I get the error message from above when i try to connect to the CRM via SDK calls.

I have tried to apply the following KB-Article. Which worked for CRM 2011 and AD FS 2.1,

http://support.microsoft.com/kb/2828015/

But the Script fail with the following error message:

VerifyConfigurationEntityIsNotAmbiquous raising error : This setting has multiple instances. The Id of the instance is required to set or get the ActiveMexEndpoint property. 

The error occurs at the following line of code:

$Id=(Get-CrmAdvancedSetting -ConfigurationEntityName FederationProvider -Setting ActiveMexEndpoint).Attributes[0].Value 

OS: Windows Server 2012 Standard

Did anyone solved the issue?

best regards,

Martin
