Could someone help me out with how to configure Zimbra to failover to another Zimbra LDAP instance if LDAP fails?
I've inherited a Zimbra NE 5.07 server from my predecessor who also installed two other Zimbra services which just run the LDAP service. I've checked those servers and they're both replicating properly. They also show up in the Zimbra web admin.
The problem is that a few times recently the openldap service on the main server has simply died (which I must say is unique in my experience of openldap). I've not been able to find the cause yet, but the worrying thing is that Zimbra doesn't fail over to one of the slave servers; the whole zimbra server simply stops working because of the (I suppose) large amounts of configuration data it needs to retrieve from ldap.
The only thing I could find on the wiki that comes close to failover is a manual slave to master promotion, which is no good to me. (http://wiki.zimbra.com/index.php?tit...to_LDAP_Master)
Looking through the various configs, all the services seem to be configured to just use a single ldap host for lookup (for example, postfix's ldap config could read "server_host = ldap://server1.place.com, ldap://server2.place.com" instead of just "server_host = ldap://server1.place.com".
So perhaps Zimbra doesn't support failing over like that?
Any help would be appreciated.
