| |
|
| |
|
| ====Solution:====
| |
| Need to manually change the for parameter olcserverid and reimport the config.back file to make the id different.
| |
|
| |
| '''Step 1:'''
| |
| Take the backup of main database and configuration database manually from LDAP1.
| |
| /opt/zimbra/libexec/zmslapcat /tmp
| |
| /opt/zimbra/libexec/zmslapcat -c /tmp
| |
|
| |
| '''Step 2:'''
| |
| Make the change in "'''/opt/zimbra/data/ldap/config/cn=config.ldif'''" file, Set different ID (1) for the olcserverid parameter.
| |
|
| |
| '''Step 3:'''
| |
| Reimport the configuration database and main database on LDAP1 server.
| |
| cd /opt/zimbra/data/ldap
| |
| mv mdb mdb.old
| |
| mv config config.bak
| |
| mkdir -p mdb/db
| |
| mkdir config
| |
| /opt/zimbra/libexec/zmslapadd -c /tmp/ldap-config.bak
| |
| /opt/zimbra/libexec/zmslapadd /tmp/ldap.bak
| |
| mv accesslog accesslog.old #On both Master LDAP server
| |
| mkdir -p accesslog/db #On both Matesr LDAP server
| |
|
| |
| '''Step 4:'''
| |
| Restart the services.
| |
| zmcontrol restart
| |
|
| |
| '''Step 5:'''
| |
| Now again check both ladps are in sync.
