<P>
On most systems it doesn't matter what the numeric user and
group ids are, but if you use the Network filesystem (NFS),
you need to have the same uid and gid on all systems. This
is because NFS also identifies users with the numeric uids.
If you aren't using NFS, you can let your account creation
tool pick them automatically.
<P>
If you are using NFS, you'll have to be invent a mechanism
for synchronizing account information. One alternative is
to the NIS system (see [<A HREF="node113.html#network-admin-guide">Kir</A>]).
<P>
<b>META: </b> this is wrong place?
However, you should try to avoid re-using numeric uid's
(and textual usernames), because the new owner of the uid
(or username) may get access to the old owner's files
(or mail, or whatever).
