Hi all,
Looking to pick your collective brains.
At work we're looking into deploying an ldap server and I've been tasked
with working out the pros and cons of Sun ldap server vs, openldap.
So far, the major problems I've heard about (no data to back these up) is
that with openldap some of the upgrades can break previously existing
schemas, and that if it crashes youc an lose data, although I seem to
remember hearing that openldap recently went to totally atomic
transactions?
Sounds like what you heard about data loss refers to people using the LDBM
backend, which is similar to the backend used by Sun. OpenLDAP has very
robust and consistent backends these days (back-hdb and back-bdb).
Although if you are referring to Sun's new Java DS, that may not apply. ;)
In any case, I've not heard of schema breaking on upgrades, either. Going
from version 2.0 to 2.1 did implement stricter schema rules, so that schema
that were *invalid* to begin with needed to be fixed so to be correct via
RFC.
In short, what I'm looking for is a comparison of the two offerings. I
have googles, but come up enmpty so far. Would anyone here have any
suggestions where I might look?

Stanford dropped its Netscape (precursor to Sun) directory servers for
OpenLDAP several years ago, and it has performed phenomenally, and
continues to provide robust, scalable performance.
