It can certainly cause problems on servers. If you have one group per user,
and things get confused with more than one user being associated with a
group (usually mistakes by admins less familiar with Unix)... You then
delete the user with "userdel", and it won't delete the group. You then
try to add that user back in and it will barf because the group already
exists.
Just switched a customer's box to doing a single group ID per user last
week because of that.
