We are seeing an issue with F14 DS where it has been built against
opneldap libraries while we still have plugins built against mozldap.

We have a patch that should be solving some issues against ipav2, if
that checks out we will se if we can backport them to ipa 1.2.2 but it
may take a little while.

Meanwhile you may want to try to downgrade 389-ds (make sure you
backup your data first).

Simo.
