Watch out, there is now a hard-coded limit of 3000 valid logged in users
at a time.  It was added becouse of the way we allocate 'terminal names'
for PAM and utmp.  Also, the way these are allocated is by attempting to
insert numbered records into a tdb sequential from zero.  (ie highly
inefficeint).  If your running massive numbers of concurrent users you
may wish to look at the code in smbd/session.c.

Technicly, PAM does not need the terminal name, but it gets it becouse
much of the time we are going to calculate it for utmp anyway.
