This bug is created as a clone of upstream ticket:
In case you have multiple servers defined in sssd.conf, it might happen that no failover takes place. When a connection to one server can be established and port 389 is reachable, but when the ldap search times out, sssd does not mark the connection as bad and keeps talking to this server instead of failing over to any of the other servers defined in the configuration.
