Configuring Zimbra Servers to Use LDAP Replica

To use the replica LDAP server instead of the master LDAP server, you must update the ldap_url value on the Zimbra servers that will query the replica instead of the master. For each server that you want to change:

1.	Stop the Zimbra services on the server. Type zmcontrol stop.

2.	Update the ldap_url value. Enter the replica LDAP server URL

zmlocalconfig -e ldap_url=”ldap://<replicahost> ldap://<masterhost>”

Enter more than one replica hostnames in the list typed as ”ldap://<replicahost1> ldap://<replicahost2> ldap://<masterhost>”. The hosts are tried in the order listed. The master URL must always be included and is listed last.

3.	Update the ldap_master_url value. Enter the master LDAP server URL, if not already set.

zmlocalconfig -e ldap_master_url=ldap://<masterhost>:port

Additional Steps for MTA hosts.

After updating the ldap_url, rerun /opt/zimbra/libexec/zmmtainit.

This rewrites the Postfix configuration with the updated ldap_url.
