Well, why do you really need that? I don't have client-side sorting in
web2ldap because it won't scale with large search results. Some of my
customers have more than 100k person/user entries in their directories.

The function DelTree() is in pylib/w2lapp/delete.py. If the tree
deletion control cannot or shall not be used it also makes use of some
operational attributes (e.g. hasSubordinates etc.) to determine whether
a found entry is a leaf-entry.

Bear in mind that I started learning Python when the first code was
written almost 11 years ago. So I have to admit that many parts are
really ugly code and not really good programming examples.

Ciao, Michael.
