If a customer reports such a problem, Red Hat will respond.

It is not meant to impress, just a statement of fact that the RHEL
OpenLDAP 2.4.23 is not a stock 2.4.23, but contains many patches
backported from 2.4.24 and later.

Many, not all.

I did not mean to imply that more patches == better. I just meant more
patches == not stock 2.4.23.

If you will concede the point that quantity != quality, then so will I.

So moving from OpenLDAP 2.4.x to 2.4.x+1 does not introduce any new
features or regressions, ever?
If this is really the case, then why would Debian or any other
distribution not want to rebase every time OpenLDAP has a 2.4.x+1
release? The FAQ says ". . . upgrading to newer versions is often
desireable but also means introducing change into stable releases, which
is exactly opposite to the point of release stability". So it's ok for
Debian to take a hard line for release stability, but not Red Hat? Or
is your problem really that Red Hat doesn't openly proclaim that the
OpenLDAP server included with the distribution is not for "a large site,
a complicated installation" or the like? So if Red Hat were to provide
such a disclaimer, it would be ok for Red Hat to take a hard line for

So what's the difference between Debian and Red Hat with respect to
OpenLDAP? That is, why bash Red Hat's handling of OpenLDAP and not
Debian stable? I suppose the same thing applies to Red Hat - if a Red
Hat customer has "a large site, a complicated installation, or problems
for which [they] need to seek help here", they will probably be willing
to pay extra for extra attention, in the form of adding additional
resources to build and maintain OpenLDAP themselves, or hiring a firm

Most of the complaints I see from users in the OpenLDAP community are
about the TLS/SSL support in RHEL6. Do you have evidence to the contrary?
As for other comments, see below.

I see your point. I get it - the OpenLDAP community is not happy with
the way Red Hat handles OpenLDAP. If you are really, truly concerned
about Red Hat customers using OpenLDAP software, what are you going to
do about it? If your goal is to get Red Hat to rebase OpenLDAP
releases on a regular basis, how can you achieve that goal? Complain to
Jan and I in an OpenLDAP ITS? Bash Red Hat to every user who has the
temerity to use rhel/fedora/centos and ask a question in #ldap and
#openldap and the OpenLDAP mailing lists? If a critical mass of paying
Red Hat customers tells Red Hat that they are not happy with OpenLDAP,
then Red Hat will do something about it. That's the demand side.
Red Hat (and probably all OS distributions) has the same problem to some
extent with all upstream projects. There are probably Apache upstream
community members who are unhappy with the way Red Hat deals with Apache
As for the supply side, if Jan and the other OpenLDAP maintainers feel
that it is better to rebase than patch, then that's a good start. They
are the ones who are on the hook - it's their necks if things don't work
correctly. Once they convince themselves, then they have to convince
QE, Doc, support, and management that it really is the best policy. And
part of it is Red Hat's policy towards release stability, which adds
additional process, but is workable.
