Here is my /etc/snmp/snmpd.conf (I did change the sensitive data to 
something arbitrary):
master agentx
mibdirs +/usr/share/dirsrv/mibs
syscontact software at ourdomain.com
syslocation LOCATION
rocommunity 34k5j6g7 127.0.0.1
authtrapenable 1
trapcommunity public
trapsink 127.0.0.1

Did you have something like this in mind for the communication problem ?
2009-11-30 15:21:36 Warning: Failed to connect to the agentx master 
agent (/var/agentx/master): Unknown host (/var/agentx/master) 
(Permission denied)

That did happen at the start.

After we resolved that issue, this is what the logs show
2009-12-04 13:47:21 Reloading stats.
2009-12-04 13:47:21 Opening stats file 
(/var/run/dirsrv/slapd-server-users.stats) for server: 389
