Thanks for the reply.

First, how would I rpmbuild my openldap v2.4.x as a standard CentOS 5 
package (i.e. replacing native openldap-2.3.43-25)? If I were more 
experienced, I could have tried to engineer 
openldap-2.3.43-25.el5.src.rpm to upgrade the system to use 2.4.x... But 
still, I haven't seen any OpenLDAP packages attempting to do so, 
probably because of the tight integration of CentOS with some openldap 
v2.3 libraries.

I think it's good that third-party packages (even of the same software) 
give the ability to not mess with standard system. The same is true for 
reputable Symas OpenLDAP packages.

So, I simply use LTB OpenLDAP, even though it's installed at 
non-standard locations.

(This has an added benefit of easy migration. You can setup any/all of 
those on the same system and decide which one to enable at any time.)

I like CentOS from many aspects as an enterprise server OS. I wouldn't 
change it.

Yet, it's important to me to be able to build/combine non-standard 
packages. Even with CentOS 6, I would still continue to use LTB OpenLDAP 
for a number of reasons.

It's true that I've invested much effort in this task, but mostly 
because my knowledge on this subject is very basic.

Note that Dovecot RPM works fine as is (compiled with OpenLDAP 2.3), 
i.e. there is no real need in re-building it using OpenLDAP 2.4 libs. We 
just try to make things better (and make our life a bit more difficult) :-)

True, but I am hoping that there might be some Dovecot RHEL/CentOS 
packagers in this list, and that would help resolve issues more 
effectively, as it is a Dovecot-specific (even if for a package thereof) 
question.

So, any help will be appreciated!

Hmm, I can't tell. I hope atrpm packager(s), if present on this list, 
can provide some feedback.

Thanks again,
