Subject: [PATCH] Fix ldapupdate.get_sub_dict() for missing named user
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The named user may not be present when ipa-server-dns and bind are not
installed. NAMED_UID and NAMED_GID constants are only used with local
DNS support.
