Subject: Patch: Bugs with back-ldap/meta mappings

Full_Name: Hallvard B. Furuseth
Version: HEAD
OS: Linux
URL: http://folk.uio.no/hbf/OpenLDAP/back-ldap.txt
Submission from: (NULL) (158.36.148.34)


The source claims the 'map' attribute has syntax
map {objectclass | attribute}   {<source> | *}      [<dest> | *]
while it actually has syntax
map {objectclass | attribute} [<local name> | *] {<foreign name> |
*}
except that the code is confused about it.  Removed attributes are
put in both the maps for local and foreign names:
	# Remove description and present title as description instead
	map attribute	description
	map attribute	description title
-->
	slapd.conf: line 10: duplicate mapping found (ignored)

Also, map.c:ldap_back_map_attrs() loops forever on removed attributes
(ie. if one asks ldapsearch for an attribute which has been removed).
