Modified by me to dn_*() and attr_*() functions and to use
uidObject and to handle search scopes better. Could use some
more work. A fun project for anyone wanting to learn how
backends work.
Modified dn_parent and dn_rdn to accept be=NULL (to bypass
be_issuffix check). These functions should be generalized
and moved to -lldap. A project for another day.
