Max UID's on RHEL 3

[Esquivel, Vicente]

Hello all,
 
Is it possible to have more then 60,000 UID's(user accounts) assigned on
a RHEL ES 3.0 system?  The systems by default has a UID_MAX of 60,000 in
the login.defs file.  Is it possible to have more, if so how many is the
true max?  What changes would I have to make to the system to accept
more?  I hope someone can help as this is something we have run into and
need to try to fix promptly.  Any advice on this would be greatly
appreciated.
 
Thanks all in advance
 
Vince
