ps displays uid number instead of name

[Richard Riley]

I have just noticed on a couple of my RHEL 4 servers that when I run the
"ps" command it displays the uid number instead of the userid name for
some users.  I have these same users on other RHEL 4 servers (same
version) and everything is displayed normally.  The user names that I
have problems with are all over eight characters long.
This is not a big problem, but it is annoying to have to lookup the uid
number in the password file to determine the user associated with the
process.
