Description of problem:
I have a system that is to be used as a samba server but forget samba
and consider core os users.  I have a user called administrator and
when this is used there are all kinds of problems such as problems
with groups where administrator is a member and other problems.

Version-Release number of selected component (if applicable):


How reproducible:
Create quite a few groups - 100 ish and add the user administrator to
those groups.  You will find that administrator can only get into so
many of the groups - a certain depth down the list but no further.  I
am assuming that the word administrator is a key word and should not
be used for users or group names.  I wondered if it affects a certain
number of groups - maybe that the top 40 are considered system groups
and it is ok in those and after that it is not used.

A strange problem I know but it is there

Steps to Reproduce:
1. Create 100 ish groups - in our case 100 users with a group the same
as the username and make the owner the user and the group the owners
group.
2. Add the user administrator to each users group and try to gain
access to each home directory
3. It should work until you are so far down the group list and then it
should give access denied.
  
Actual results:
Access denied after so many groups

Expected results:

Access to all groups.

Additional info:
Seems to have been a long time problem with older versions of redhat
8, 9 and fedora.  Not sure if it is a bash problem - not sure what
users and groups fall under.
