Symptoms

Assume that you have a client computer that has a cached locked-out account in a Windows Server 2008 R2-based Active Directory Domain Services (AD DS)environment. When you try to log on to the computer by using a smart card, the behavior differs from the behavior that occurs if you log on by using your username and password.

Consider the following scenarios.

Scenario 1

  • You use a smart card to log on to the cached locked-out account. The logon fails, and you receive the following error message:

    The system could not log you on. Your account has been disabled. Please see your system administrator.


  • You disconnect the computer from the AD DS environment, and then you try to log on again.

In this scenario, the logon fails, and you receive the following error message:

The system could not log you on. The domain specified is not available. Please try again later.



Scenario 2

  • You use your username and password to log on to the cached locked-out account. The logon fails, and you receive the following error message:

    The reference account is currently locked out and may not be logged on to.

  • You disconnect the computer from the AD DS environment.

In this scenario, the logon succeeds by using your cached credentials.

Cause

This problem occurs because the Key Distribution Center (KDC) sends a KDC_ERR_CLIENT_REVOKED error only when you use your smart card to log on to the locked-out user account. This error message is mapped back to the STATUS_ACCOUNT_DISABLED value. This causes the cached account to be reported as disabled on the computer. The related cached credentials are then deleted.
