We have a SUSE 9.0 server with some errors listed in /var/log/messages like these:

Feb 19 13:49:02 server2 /usr/sbin/namcd[6432]: ldap_initconn: LDAP bind failed, trying to connect to alternative LDAP server
Feb 19 13:49:02 server2 /usr/sbin/namcd[6432]: ldap_initconn: Unable to bind to alternative LDAP servers either.
Feb 19 13:50:01 server2 /USR/SBIN/CRON[26656]: (root) CMD (/opt/novell/zenworks/bin/zeninvchown > /dev/null 2>&1 ||

The messages are repeated every minute. We have looked through many log files and tried to gather enough information to identify a solution that will make the bad messages go away. Server2 is part of an eDirectory cluster and also runs a post office, Zenworks 7, and secondary DNS. My question is - what tools can I use to identify where the exact problem lies? We have verified that the Zenworks inventory service fails whenever we try to start it, but there are no helpful error messages in the logs we checked. Users can authenticate to our eDirectory master server, so we believe the namcd service is a server-to-server authentication issue.
