Normal Logging behavior?

Is it normal for Jive to execute these queries on users even though many aren’'t and have never logged into the server before?

These entries are from the debug log file and this behavior is happening every 6 hours or so. It doesn’'t query every user in our LDAP…only users that I have added to roster groups. Anyone else seeing anything similar?
