Well there is that handy "access_attribute" setting in the LDAP module...

I'm pretty sure what you've just described isn't possible within the LDAP protocol, or at least not done by any LDAP server I'm aware of.  But if it's visible to the LDAP client, send over a PCAP and I'll add support so that it's at least logged...
