Title: #636: failover: tune up default timeouts
The defaults are the problem. Mostly I don't like that the LDAP operation time out is
24 seconds, but the fail over timeout of 18 seconds is also too long.
If the server was really slow or was dropping (not rejecting) packets, then the fail over
would take almost half a minute, that seems just too much.
btw why is the ldap timeout the longest? I thought that the top-level timeout was the
failover one which gives you a server? Or is the LDAP timeout used for something like
sdap_op which includes the server resolution with failover and then LDAP connection?
