70sortctrl.t

#!perl
#
# For this test to run you must defined the following in test.cfg
#   $EXTERNAL_TESTS = 1
#   %sortctrl with the following entries
#     host   => name of ldap server
#     base   => the base for the search
#     filter => the filter for the search
#     order  => the attribute name to order by
#
# The attribute given must have unique values over the entries
# returned from the search. This is because this test checks
# that the order of entries returned by 'attr' is the exact
# opposite of '-attr' this is not guaranteed if two entries have
# the same value for attr.
#
# Obviously the filter should be specific enough to ensure that
# a relatively small set of entries is returned
#
# TODO:
#
# This test should be expanded to test sort controls with
# more than one attribute specified.
