We just found that all cron jobs at 0,10,20,30,50 every hour would fail
consistently and give the error in my original post, but any other
minutes all cron jobs are OK.
We are using nss_ldap_226-18 and crontabs-1.10-7. I will check if UID
not found problem occurs also at 10th minutes.

Subject: Random UID not found problem
Some of our users get "UID xxxx not found" message when they open a
new terminal or run a rsh command, it appears a few times a day and
it is mostly just annoying message because users can continue to work
as normal, however, sometimes It also causes cron jobs to fail,
In system log, it shows,
crond(pam_unix): could not identify user (from
crond: User not known to the underlying authentication module
We are using Fedora DS 1.0.4, and clients are RHEL 4.5 . This problem
started ever since we switched into LDAP three months ago.
