Hello Brian,

are you sure you want to go with /etc/passwd?
You're talking about >60k users. Maybe you should look at LDAP or an
equivalent solution. Especially if you are going to set up other
machines with large user-bases it will simplify management a lot. 
With LDAP you can manage users, groups, group-membership and the like in
a central directory. You can even configure sendmail, autofs and other
services to lookup data in the directory (which makes the whole thing -
at least imho - much easier and straightforward to manage).

Regards,
Andreas
