Define min UID as 600 in the file:
/etc/login.defs

Then for all UID's below 600 the purge script will not work. We use this
to define admin users and regular users. Admin users are allowed to
login multiple times.

Alternatively /usr/sbin/purge_user needs to be modified so that it only
picks up UID's above 600.
