The following is nothing more than a guess and speculation : <speculation type="mine"> It may be a throw back to the days when an int was 16 bit and userid's were an unsigned int in the kernel (65535 being your largest uid). I seem to recall an annoyance/bug in the NeXT OS in which the userid was defined as a signed int so the max uid was 32767, and nfs'ing between NeXT and Sun could be problematic if you had a userid of 44569, but I digress. If this is in fact nothing more than a throw back, and uid in the linux kernel is now a long or unsigned long, then you will be able to have userid's up to 2^31 -1 or 2^32 -1. Im too lazy to look, maybe someone else knows. </speculation> Other than that, I have no idea :-). Wayner >>> Esquivelv@xxxxxxx 07/04/06 12:13 pm >>> I think I might have found the answer on my own, I tested my RHEL 3 server and I was able to increase the UID_MAX to almost any number I wanted and I was able to create accounts. The server kept on automatically assigning UID's to the accounts and I was able to login with the accounts just fine. I got all the way up to like 12345678901 as a uid and it allowed me to assign it. Anyone have any input on this at all good or bad about huge amounts of accounts on a server?
