- 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 :)
