LDAP Replicas 4.5.x to 5.0.x

Revision as of 23:00, 28 January 2008 by Mmorse (talk | contribs)

ZCS 4.5.10 (and older): If upgrading to any ZCS 5.0.x (5.0.0, 5.0.1, 5.0.2 +) please use the workaround below.

This procedure allows all the replica servers to properly preserve the changes made to the master during the upgrade process and allows ZCS 5.0.x non-LDAP servers to work with the 4.5.x replica servers.

Choosing to remove your LDAP replicas during the upgrade and install fresh ones is also an alternative if you wish.

4.5.10 (and older) > 5.0.0 or 5.0.1 workaround:

If you have LDAP replica servers configured for ZCS, when you upgrade from 4.5.x to 5.0, you must modify each LDAP replica server before you upgrade the LDAP master server.

1. On each LDAP replica server perform the following:

Stop LDAP, as the zimbra user, type ldap stop
Change directors, type cd /opt/zimbra/openldap/etc/openldap/schema/
As the root user, type mv zimbra/schema zimbra.schema.old
As the root user, type wget http://files.zimbra.com/downloads/5.0.1_GA/zimbra.schema
As the root user, type chown zimbra:zimbra zimbra.schema
As the root user, type chmod 664 zimbra.schema
Restart the server, as the zimbra user, type ldap start

wget isn't available on macs. Use curl -O instead

2. Upgrade the LDAP master as described in the release notes

3. Upgrade the LDAP replicas

Fix for those who have already upgraded from 4.5.x to 5.0.1, and the replicas become out-of-sync:

On the Master:

  su - zimbra
 /opt/zimbra/openldap/sbin/slapcat -b ' -f /opt/zimbra/conf/slapd.conf -l /tmp/ldap.ldif
 scp /tmp/ldap.ldif root@replica:/tmp/ldif

On the Replica:

 chown zimbra:zimbra /tmp/ldap.ldif
 su - zimbra
 ldap stop
 mv /opt/zimbra/openldap-data /opt/zimbra/openldap-data-old
 mkdir /opt/zimbra/openldap-data
 cp /opt/zimbra/openldap-data-old/DB_CONFIG /opt/zimbra/openldap-data
 chown -R zimbra:zimbra /opt/zimbra/openldap-data/
 su - zimbra
 /opt/zimbra/openldap/sbin/slapadd -w -q -b ' -f /opt/zimbra/conf/slapd.conf -l /tmp/ldap.ldif
 ldap start
