cron does LDAP query for local user


We've got crontabs set up in /etc/cron.d to run various things, and we have them running as a specific local user.

Watching the LDAP logs, I can see the servers in question making requests for that username to the LDAP server every time cron runs, even though that user isn't in LDAP and is only local. nsswitch is configured to do "files ldap" as well.

The constant stream of LDAP queries is killing LDAP and making it impossible to log into our boxes.

Anyone have any idea why cron is querying LDAP for a local user?

As a point of interest, I documented the same characteristics on AIX 5.3 yesterday. A local account generated ldap traffic when a performance gathering script was run from cron.
