BTW - 1. Should have added RH7.2....
2. A new clue, the highest UID I can change to is 3590!?!?!
3. Sorry for having to hide the real names/numbers.
I have added a new user which requires a specific UID.
useradd -c "Example Agent Account" -g eaa -d /eaa -u 6000 examp03
Trying to login using Putty I enter the ID and password then get:
PuTTY Fatal Error - Server sent disconnect message: "Command terminated on
signal 25."
Using usermod I knock the UID down to a low order number and I can log in
correctly.
usermod -u 511 examp03
This tells me there is probably a MAXIMUM UID so I looked in /etc/login.defs
and found:
UID_MAX 60000
which is well above my 6000 number.

I've upgraded openssl and openssh to match a similar system and it works
just fine.
Any ideas where I can look next???
Thanks
