I've been told that it work just fine to extend it for slapd.  It should
thus work to add 'ulimit -n 8192' in /etc/default/slapd.

No-one else experience problems like this with Debian Edu/Lenny?

I see a problem with OpenLDAP spending 100% CPU and not responding to
requests for a long time.  My local OpenLDAP expert sent me to
and <URL:http://www.openldap.org/its/?findid=6856> which might be
relevant.  I have not had time to test yet.  Anyone else experience
hanging OpenLDAP in Lenny?
Happy hacking
