SYMPTOMS
Consider the following scenario:
- You try to log on to a Microsoft Windows Server 2003 or Microsoft Windows XP workstation as a trusted Massachusetts Institute of Technology (MIT) Kerberos realm user.
- Your MIT Kerberos realm user account is mapped to a Windows account.
- You enter the wrong password.
In this scenario, the Kerberos client ignores the KRB_AP_ERR_BAD_INTEGRITY return message, and then tries to log on three more times with the same credentials. If an account lockout policy is enabled in the MIT Kerberos realm, this causes four bad passwords to be counted for each bad logon on the client workstation.
