crond dies when ldap user changes crontab

[Unix Administrator_5]

We are running rheles 3.0. We have users configured in Openldap 2.0.27 running on a rhelas 2.1 server. It seems that when a user changes their crontab that crond dies. We get this in the cron log:

Dec 2 13:25:00 quigon crond[22393]: nss_ldap: reconnecting to LDAP server...
Dec 2 13:25:00 quigon crond[22393]: nss_ldap: reconnected to LDAP server after 1 attempt(s)

It only happens for users in ldap. Any ideas?

Thanks -- Jon

It may help to have the name service caching daemon (nscd) running.

Is it running:
service nscd status

If not, is it configured:
chkconfig --list nscd

If not:
chkconfig --add nscd

Enable it:
chkconfig nscd on

Start it:
service nscd start

This is not a fix, but may help.
