First, let me state, this was an IT goof up. They deleted an account, went "oops" and created a new account with the same credentials. I can't fathom why.
Regardless, I've got a Linux (Ubuntu Server 10.04) box authenticating against an active directory server, and users logging in have local home directories and such.
I'm stuck with one user name having a new UID (or SID in AD jargon). Over and above
chowning his home directory, what other interventions should I do?
