System is Ubuntu 6.06 LTS
ZCS 4.5.9 NE.

Brought up a second server and set the ldap Master to be server 1. Replication works fine. Zmmailboxmove works back and forth etc, etc.

I've attempted to Promote server 2 to become the master following these intructions:
Promoting Replica to LDAP Master - Zimbra :: Wiki

I've adjusted this last step to be:
/opt/zimbra/libexec/zmmtainit <server2.fqhn>
instead of
/opt/zimbra/libexec/zmmtainit XX
Upon restarting the services I receive the following error and ldap never starts again:
Failed to start slapd.  Attempting debug start to determine error.
daemon: listen URL "server2.fqhn" parse error=3
Not quite sure where to go from here?
