It sounds as though there are files on your servers owned by a UID or GID
(most probably a GID) that is not in /etc/group, and is being looked up and
"reverse resolved" to 'NT AUTHORITY\Authenticated Users', but this somehow
doesn't map back the other way, i.e. from a name to a GID.
Can you narrow it down and perhaps use the 'find' command to see what
UID/GID this is?
