Depends on the backend being used. For instance, back-passwd
generates entries based upon getpwent(3) library calls which
may be backed by simple flat files, or backed by some
password management system. However, I assume you are asking
the question in respect to back-bdb (or maybe back-hdb or
>(structure of file) is it some like hashfile, index file, or some
>representation of tree (AVL tree) ???
The short answer (for back-bdb) is that entries are held a
BTREE bdb, the DN index is held in a BTREE bdb, and indices
for an attribute are held in a BTREE bdb. All bdb of slapd
"database" are contained within one DB_ENV.
For more information about BDB BTREEs, see the Sleeycat
BDB documentation <http://www.sleepycat.com/docs/ref/toc.html>.
