"Authenticated Users" is not a local group, nor a builtin group.  It's
one of the so called "well known SIDs", see
http://msdn.microsoft.com/en-us/library/aa379649.aspx
These well-known SIDs are not enumerated in calls to NetGroupEnum nor
in calls to NetLocalGroupEnum.  That's why they are missing in /etc/group
in the first place.  And usually you don't need them in /etc/group.
