But it seems to make much sense: In my experience if you configure multiple LDAP servers, the NSS resolver always uses the first configured server as long as it's reachable; even if it's not, the first configured server is tried first. After connection timeout the second server is tried... We had dhad a case when all LDAP operations were heavily delayed when two out of three servers had failed (due to rebooting the machine).
