Multi Server Install : Authentication threw Replica Ldap

Postby brano » Fri May 29, 2020 1:43 pm

Hi Everybody,

I currently set up a multi-server zimbra environment in order to validate some features. Here is my configuration :
-2 MTA/Proxy servers
-2 Store/WebUI servers
-1 Master Ldap server
-1 Replica Ldap server

I use the latest zimbra distrib : FOSS 8.8.15. For my availability tests, i need to know what is happening when Master Ldap is down. Currently, when i stop the master ldap, users are not able to authenticate threw AdminUI or WebUI.
I followed zimbra guide and changed ldap_url and ldap_master_url. The passwords are the same for the two ldap servers. (amavis, bes, root ...)
The replica is synchronized with master.

Somebody knows if it is possible to authenticate a mailbox user when ldap master is down ?

Below, maybe it's a clue. It's what i obtain form the zmreplchk command :

When master is down :
[zimbra@Test-DB02 ~]$ libexec/zmreplchk
Replica: ldap://test-ldap02.domain.com:389 Code: 6 Status: CSNs:
20200529093240.802347Z#000000#000#000000

When master is up :
[zimbra@Test-DB02 ~]$ libexec/zmreplchk
Unable to bind to master (ldap://test-ldap01.domain.com:389): Please set ldap_master_root_password

I have search for this error, i found some informations on ldap password, but passwords are the same...

I stay at your disposal for any others informations,
Thanks, Best Regards and have a nice week-end!

Have you defined your group of ldap servers in ldap_url via zmlocalconfig ?
