As far as I know, you won't be able to have an all numeric userid.  This is
because behind that the system will identify the user with their uid which
is an integer and is all numeric.  Now, if the user has userid 1342 but user
4536 has uid 1342 which user is the system looking up?  Is this a uid number
or a userid?

Even prefixing every ID with a letter before it's dumped to the Linux
passwd/shadow files will solve that issue for you.
