My initial ideia was to use BDB, but on openbsd mailing (my OS is
OBSD) i heard someone telling me he/she did not trust BDB and
preferred some variant of gdbm/ndbm.
a couple of years ago, perhaps..., BDB 4.2.52p2 runs very fine with
several hundred of thousand accounts and thousand machines (samba and mail).
And, of course, the BDB runs very fine only if it is well tunned (for

others) in the faq-o-matic
So my question is how reliable you judge openldap + bdb?\
I know this may seem a little hard to answer, but i am planning a Dell
PowerEdge 750 with SCSI RAID 1, 512 MB RAM and obsd 3.7. It will be
used for handling about 10K users and 3k desktops for qmail, linux and
It my configuration realistic?
Strongly recommend you 2 servers (a master and a slave, also for HA),
with a bit more of RAM (1-2GB perhaps). You need a lot of indexes and a
lot of memory makes the ldap flight.
The transaction logs may be in a different disk for I/O performance.
