i have a question :

if i use openldap 2.1.19 + db4-4.2.52 of fedora distro developing ? and 
use cyrus-imapd-2.2.3, all work fine after this update ? or is the best 
remaining into 4.1 of default distro... 


is really "safe" install the db4 4.2.52 and tcl-8.4.x of fedora  , on a 
rhe 3.0 ? (whitebox linux)

or tcl and db4 affect other applications on the system , will not work 
after the upgrade ?

if someone give some advise before update the db4 ... i scare with these 
post...i have a smp system with htreading.
Thanks again.

First, you need DB4.2 if you have anything SMP or multithreaded :)

Second, see this:

Other searches in the openldap-software ML archives will give you
more hints on how to configure bdb for OpenLDAP, and from there, for
Cyrus and any other app.
