I've played around with integrating Linux against Active Directory quite a long time ago and made this work with a couple of machines, so I know it's possible and that it can be done a couple of ways, including WinBind with NTLM or Kerberos.

Authenticating is the relatively easy part, but what I want is a way of keeping the same UIDs across all the Linux boxen. I have looked across lots of web searching and things I have bookmarked but they focus more on the authentication and the local separate UID/GUID maps kept by each individual linux box.

Does anyone know anything about the UID mapping across all linux boxen so that the same user account name and login will get the same UID across all machines?
