This can be done in Python, it is essentially an ACL modification.
This is in source4/dsdb/tests/python/user_account_control.py:
self.sd_utils = sd_utils.SDUtils(self.admin_samdb)
self.admin_samdb.create_ou("OU=test_computer_ou1," + self.base_dn)
self.unpriv_user_sid = self.sd_utils.get_object_sid(self.unpriv_user_dn)
mod = "(OA;;CC;bf967a86-0de6-11d0-a285-00aa003049e2;;%s)" % str(self.unpriv_user_sid)
self.sd_utils.dacl_add_ace("OU=test_computer_ou1," + self.base_dn, mod)
Just take care, while not giving out the administrator password is an
admirable thing, someone who can create user or computer objects (the
above is for computers, you can delegate the right to create users
instead with the users GUID) still has quite some power to disrupt the

This is a different kind of delegation, this is the right to delegate
the authentication from one service to another, not the delegation of
rights to create users etc.
