Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

We are having a problem where our OS X Lion machines will continually query Active Directory 2008 for every user in the directory until a user logs into the machine. When a user logs into the machine, the continuous, expensive queries stop. The problem queries start again as soon as the user logs out. This is a significant load on the domain controllers (DCs) and triggers Field Engineering 5 events on the DCs. We do not use OS X Server Lion.

I would look at two things. 1. Look carefully at the ldap query and filters on the client side. Experiment. 2. See if any job is running on the OS X systems that requires user information. Try to track the LDAP query down to the requesting service. –  kmarsh Apr 2 '13 at 20:57
    
Can you provide the full Event entry? All the query details –  Mathias R. Jessen Apr 19 '13 at 21:31

This question has the exact same problems as the previous one -- there isn't enough troubleshooting information for us to offer any advice. I won't mod-hammer this closed, but I doubt you're going to get any kind of good answers without more detail (like what kmarsh is asking for in their comment) –  voretaq7 May 1 '13 at 23:00
