Issue with Multi-Master LDAP Servers

[vnngoanhtuan]

Hi All,

Model: 02 master ldap server.
- Master ldap server 01: zimbra-ldap.mydomain.com
- Master ldap server 02: zimbra-ldap2.mydomain.com

Currently, I meet a issue when zimbra-ldap.mydomain.com was broken. After fixed the server zimbra-ldap.mydomain.com. I run command as below:

- On zimbra-ldap2.mydomain.com:
$/opt/zimbra/libexec/zmslapcat /tmp/Backup
$cd /tmp/Backup
$ls -l
-rw-r----- 1 zimbra zimbra 12234190 Feb 20 09:05 ldap.bak
-rw-r----- 1 zimbra zimbra 12234190 Feb 20 09:05 ldap.bak.20190220090549

copy ldap.bak.20190220090549 from zimbra-ldap2.mydomain.com to zimbra-ldap.mydomain.com

- On zimbra-ldap.mydomain.com:
$su zimbra
$zmcontrol stop
$rm -rf /opt/zimbra/data/ldap/config/*
$rm -rf /opt/zimbra/data/ldap/mdb/*
$mkdir -p /opt/zimbra/data/ldap/mdb/db /opt/zimbra/data/ldap/mdb/logs
$chown -R zimbra:zimbra /opt/zimbra/data/ldap

- Restore configuration file
$/opt/zimbra/libexec/zmslapadd -c /tmp/Backup/ldap-config.bak (Backup config on zimbra-ldap.mydomain.com)

- Restore LDAP database file
$/opt/zimbra/libexec/zmslapadd /tmp/Backup/ldap.bak.20190220090549

$zmcontrol start

$zmupdateauthkeys did not see zimbra-ldap.mydomain.com in list.

Grep ldap database and did not see the dn and cn : zimbra-ldap.mydomain.com in this database.

$ grep -r zimbra-ldap ldap.bak.20190220090549
dn: cn=zimbra-ldap2.mydomain.com,cn=servers,cn=zimbra
cn: zimbra-ldap2.mydomain.com
zimbraServiceHostname: zimbra-ldap2.mydomain.com
1k6................./Gj zimbra-ldap2.mydomain.com

Can you please give me more idea and solution to fix the issues?

Thanks,
Tuan
