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

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).
- librewrite, for string rewriting; it may be used in back-ldap
by configuring with '--enable-rewrite'. It must be used in
back-meta. There's a text file, 'libraries/librewrite/RATIONALE',
that explains the usage and the features. More comprehensive
documentation will follow.
- enhancements of back-ldap (ITS#989,ITS#998,ITS#1002,ITS#1054 and ITS#1137)
including dn rewriting, a fix to group acl matching and so
- back-meta: a new backend that proxies a set of remote servers
by spawning queries. It uses portions of back-ldap and the rewrite
capabilities of librewrite. It can be compiled by configuring
with `--enable-ldap --enable-rewrite --enable-meta'.
There's a text file, 'servers/slapd/back-meta/Documentation', that
describes the main features and config statements.
Note: someone (Kurt?) should run 'autoconf' and commit 'configure' as
my autoconf version must be different: my configures contain a number
of differences and I didn't feel comfortable in adding them :)
