[Samba] Permissions issue on domain member server (samba as an appliance)

[Greg Dickie]

OK I found an account with RID 500 but it has another username. I
inherited this AD from 15+ years ago. Everything looks fine, all the
computer management stuff works and I can manipulate permissions and
security BUT running robocopy still gives "Error 1314 Copying N
TFS Security to destination Directory ********* A required privilege is not
held by the client". I just noticed it does say the user but the client.
Hmmmm.

Thanks,
Greg
