Actually, Centos 5.1's OpenLDAP is linked to an internal copy of 4.2, as you
would have seen if you read the rest of the thread.

I have ~ 1.3 million entries on RHEL4 with OpenLDAP 2.3.43 and Berkeley DB
4.2, that has been running stably for years (well, it was migrated to 2.3
around the 2.3.17 timeframe).

However, 4.6 shows better performance.

No, it ships an internal copy of the library ...

But, then you would break any other applications linked to libldap, as Red
Hat/Fedora don't have a decent library policy.
Some users may prefer to try my 2.4 packages for RHEL5:
Which ships an internal copy of 4.6, ships all the backends, all the overlays,
ships a working test-suite, and installs in parallel with the RHEL-provided

With my packages that is unnecessary, you can in fact run 2.3 and 2.4
simultaneously on the same machine (a much easier migration path).
