Now we have migrated to two openldap (2.4.21, ubuntu lucid 64btis)
farms. One with 4 nodes (xen vm with two cpu cores, Xeon E5450 3GHz, 2 GB
of RAM) for the authentication database, and other with 2 nodes (with the
same resources than the other) for the other database.



OpenLDAP 2.4.21 is over 2 years old. I would first suggest upgrading to
a current release, given the hundreds of bug fixes since then. If you
still see load issues, I highly advise reading over
<http://wiki.zimbra.com/wiki/OpenLDAP_Performance_Tuning>.

I'd already followed the db tuning (but not the shared memmory). I'lltake a look on this.
