Well, pulling 100 results from the OpenLDAP server and sort it on the client side is not the issue. :-) Therefore this kind of comparison is not valid.

The problem is to do the paging in a sorted result set especially when result limits are configured. I see that some server implementations have this feature. But I wonder what happens if really lots of LDAP clients hit this feature. Most LDAP clients simply do not have support for it.

Ciao, Michael.
