Symptoms

Consider the following scenario:

  • In an Active Directory domain environment, you have a user account.

  • The user principal name (UPN) of the account differs from the Security Accounts Manager (SAM) name of the account. For example, the UPN of the account resembles "username@domain.com," and the SAM name of the account resembles "domain\username2."

  • The credentials are cached on a client computer that is running Windows 8, Windows Server 2012, Windows 7 Service Pack 1 (SP1), or Windows Server 2008 R2 SP1.

  • You always log on to the client computer by using the UPN method.

  • You change the password of the user account by using the client computer. For example, you press Ctrl+Alt+Del and then click Change Password.

In this scenario, your credentials that are cached in the Local Security Authentication Server (Lsass.exe) process are not updated.Note You are prompted to enter credentials to continue accessing network resources because of this problem.

Cause

This problem occurs because the Kerberos.dll file tries to compare the password change in the UPN user name format and in the SAM user name format in the Kerberos logon session. Because the UPN and the SAM name are different in this case, the credentials in the Lsass.exe process are not updated.
