Symptoms
Consider the following scenario:
-
You have a computer that is running Windows Vista or Windows Server 2008 in a Windows Server 2008-based or Windows Server 2008 R2-based domain environment.
-
You have a target domain user account that has the Do not require Kerberos preauthentication option enabled.
-
You use an account that has sufficient rights to perform a Kerberos Service for User (S4U) logon for the target domain user account.
Note The Kerberos authentication service uses a service principal name (SPN) to authenticate a service.
In this scenario, the S4U logon is unsucessful with the stated reason as a trust relationship failure. Additionally, future Kerberos S4U logon attempts fail after this issue occurs.
Cause
This issue occurs because the Kerberos credentials of the account that perform the S4U logon are incorrectly recombined based on the credentials data of the target SPN from the Kerberos Key Distribution Center (KDC) service. Additionally, this issue causes the logon session credentials of the account that performs the S4U logon to become corrupted, and future authentication attempts fail until the affected logon session is recreated.
