I have migrated the Sun One DB to my lab 389 DS. Users with a three
digit uidNumber are unable to login to Linux systems, however if they
connect to a Solaris system it works fine. If I add a fourth digit to
their uidNumber they are able access Linux systems just fine. Did I
miss a setting somewhere?

The problem is more likely to be a limitation imposed by the PAM
configuration on the Linux systems. Go look at /etc/pam.d/* and look
for lines like:
account sufficient pam_succeed_if.so uid < 500 quiet
A grep for 500 should find lots of examples. The most likely conflict
is in /etc/pam.d/system-auth. Comment the line and try again.
Once upon a time UID numbers up through 99 were reserved for the OS, but
somewhere along the line we ran out of numbers for such things as
Apache, ssh, etc. which each needed their own number. Someone then
decided that disallowing logins on these numbers was a good thing.
Unfortunately, a lot of places have extant UIDs < 500 (mine is 402).
You have two choices:
1. Change the UIDs of the logins of these users and all their
files on all the systems they use.
2. Leave them alone and "fix" every Linux system.
The problem with the second choice is that you could have people with
the same UID as system processes. When they do an "ls -l" they may see
that their files belong to "smolt" or "nagios" or similar. Also, they
would be able to edit files that perhaps should be off limits to them.
