As requested by many customers ZCP 7.1 offers support for multiple LDAP servers for better redundancy and higher availability. The Zarafa Server is using the standard libldap library for parsing the list of available LDAP servers and do all the failover logic. It is required to assure that both LDAP servers are fully updated and in sync when using the feature, as it can result is data loss when the LDAP servers are not fully in sync.

Instead of using ldap_host, ldap_port and ldap_protocol in the ldap.cfg, the option ldap_uri can be used to specify the different LDAP servers. If ldap_uri is set, the values of ldap_host, ldap_port and ldap_protocol are ignored.

ldap_uri = ldaps://ldapserver1:636 ldaps://ldapserver2:636
