KB-7107: Why doesn’t the UNIX system prompt for the user to change the password the first time they login with an AD account?

Centrify DirectAudit ,   Centrify DirectControl ,   Centrify DirectSecure ,

Applies to: All version of Centrify Server Suite

Question:
When an Active Directory user account is created with "change password at first login" is checked, why isn't the user prompted to change the password when they use SSH to login to a UNIX machine as their first login? The SSH session just disconnects.

Answer:
This is usually an issue with the kerberos ports being closed. When that happens, the system forces the account to use NTLM. In a one-way cross forest trust using NTLM authentication, Centrify isn't currently able to support the password expiration/change sequence.

The kerberos ports needed are: 
          Port 88 - UDP/TCP for Kerberos Auth 
          Port 464 - UDP/TCP for Kerberos Change Password
