Additional info:

In an Active Directory domain environment, you deploy a Single Sign-On (SSO) solution on client computers that are running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 Service Pack 1 (SP1).

The SSO solution calls the LsaLogonUser function to pass a KERB_TICKET_LOGON structure for Kerberos authentication.

In this scenario, the SSO solution does not work. Additionally, you receive an error message that resembles the following:

STATUS_TRUSTED_RELATIONSHIP_FAILURE

Note The SSO solution works on client computers that are running other Windows operating systems.
