1872371 - SSO does not work due to incorrect authscheme

Symptom

A SSO connection has been configured between two different systems, but the SSO is not working because the receiver is not accepting the tickets from the issuing system.

In the webdiagtool traces we can find errors like:

The authscheme found in the ticket does not exists. Authscheme = schemename 
20:30:56:935 Warning J2EE_GUEST HTTP Worker [@892972058]...ticket.EvaluateTicketLoginModule Authentication stack: [ticket].
[EXCEPTION]
