[Fedora-directory-users] Question on hierarchy tree deletion

Hi group,

I figured out how to sort in descending order using ldapsearch.

By default, it will always sort in ascending order.  If I need to sort in
descending then I need to add a "-" prefix before my attribute name.  (e.g.
-S -createtimestamp).

In addition, I can only get the descending search work only if I specify the
sorting to be done by the server by passing the "-x" flag.

I still have the question about what is the best way to delete a hierarchy
tree using command line utility provided by Fedora-DS package.

My current plan is to do a ldapsearch with subtree scope and sort the
createtimestamp attribute in descending order.  Then take the output and run
it with ldapdelete.

Thanks!

David
