Dear team,
I'm sorry if this is a stupid question, but I'd like to know the behavior of dovecot in a particular stuation. My questions are as follows.
In /etc/dovecot-ldap.conf, 'hosts=' field is the one which can be used to specify availabled ldap server to access from the clients to authorize. And also sevral ldap servers can be specified in 'hosts =' field as shown like below.
hosts = ldap-server1.example.com ldap-server2.example.com
※both server have the same configuration and available to replication ldap-server1(master) to ldap-server2(slave).
If this is right, how does dovecot know which ldap server is currently used? and if the master dies, how does dovecot know and switch to slave one? In addition, which one is the exact behavior of dovecot in case master server dies?
- only swithcing to the slave server
- switching to the slave server, and once the master server is reactive then switch back to the master server automatically
OS：RHEL4 U3 kernel 2.6.9-34.ELsmp openldap-2.2.13-12.el4
Thanks in advance,
