These are the error messages received when a user attempts to update the 
UID within RSAT.

First is;

"Unable to modify the object property values.

Check your credentials.
There could be a network problem.
Active Directory could be down.
Contact your system administrator."

Followed by;

"Unable to update the maximum user ID number for the selected NIS Domain."

Using ldbedit I see the max 'msSFU30MaxUidNumber: 10152'. This UID was 
just given to a user so I could receive the above error messages.

Where should I be looking to verify if this person has permission to 
update the Unix attributes? Thanks.
