We have decided to migrate our NT4 domain to an AD based domain. For the sake of caution, we decided to migrate to a parallel domain, rather than upgrade the NT4 PDC. So here's the problem, we have a Samba file server that is authenticating using Winbind. Currently all files are owned by NTDOMAIN\USER. I am having some problems already when ADDOMAIN\USER accesses files that they used to own, but no longer do. When I move the Samba server to the AD Domain, I expect that anyone left on NTDOMAIN is going to have problems accessing their files. Is this correct? Or will the files continue to be owned by NTDOMAIN\USER? Is there a way I can use the usermap file during the transition to avoid issues? If the files stay owned by NTDOMAIN\USER, is there an easy way to shift ownership to ADDOMAIN\USER? I can write a script, but the filer uses XFS ACLs, so I would effectively have to have a script walk through every ACL to make the change. -Ron
