That sounds very good. I am running Openldap 1.2.11 on a FreeBSD 4.0 Stable.
But I actually don't know if it is using threads. I installed it directly
from the ports tree. Does it have to use threads in order to use the patch
and how can I check for it? I'm writting my application in Perl and I'm not
really strong on neither c nor FreeBSD.
