Great. That text did mean anything without the knowledge that 
control:LDAP-Group is not a "real" attribute, unless you turn on those 
cacheable_xxxx attributes.

Instead, it is a magical pseudo attribute which triggers 
behind-the-scenes queries when you match on it.

Now grepping for paircompare_register in the code, it looks like there 
are some other attributes which might have similar magical powers.
