Pointing LDAP users toward OpenLDAP.org will hopefully get them to see
that not only ldbm as backend is considered obsolete and is deprecated,
but also that OL 2.0 is considered obsolete, 2.1 is obsolescent and
deprecated and the latest stable version is 2.2.23. Which uses Sleepycat
BDB 4.2.52 mandatorily.

ldbm as backend will ultimately seize up on production rigs, for a number
of reasons. So will BDB 4.1, though for different reasons (I've been
through it all myself). OpenLDAP 2.2.13 and higher with (patched) BDB
4.2.52 will keep on running for months without attention, even after
forced power-downs or -outages, with all of the advantages that you cite.
However, use of BDB 4.2.52 requires specialist configuration (DB_CONFIG)
for it to work at all satisfactorily.

Which brings me back to my own bugbear: Samba 3 people who want to use the
ldapsam DB backend should first and foremost be LDAP specialists, only
subsequently adapt their Samba installation to their already successful
LDAP implementation. I don't see how the Samba people can write all this
up in the standard docs and there is no single HOWTO on the subject.
