that's a no brainer. You don't remove, touch or do anything with the
openldap rpm's unless yum installs updates...they simply aren't used. If
you install everything in /usr/local (i.e. openssl/kerberos/db4/cyrus-
sasl), then nothing is affected by updates and openldap runs within its
own environment.

perhaps someone is and they'll sound off. I know that Tony Earnshaw is
doing it on RHEL

I see that listing but of course, they now have 2.3.12 in downloads as
stable...unfortunately, they seem to have frequent updates when they
introduce a bunch of new features (2.3.x) and there's still a number of
things that are not working as planned. The tag 'stable' is a curious
one since all of them that are involved in the development are
undoubtedly still using 2.2.x for their main directories at this point
and the only one that I recall that has made the commitment to 2.3.x was
Dusty Doris. But 2.2.x is feature frozen and unlikely to see anything
more than security updates and if they refuse to put out security
updates for 2.2.x, it will be awkward for RHEL4.
