This is currently how PADL nss_ldap works.  Whenever it needs to talk to a 
ldap server, it tries the server list in order.  It doesn't maintain state 
about which servers in the list are down.  If the first server in the list 
is up, you'll get the fastest response.

The bind timelimit specifies how long it will try binding to each server in 
the list.  Setting this lower will give you better response time if the 
first server is down.

There are some comments in the notes for PADL's latest nss_ldap release 
about "more robust failover support".  If you like, you could try the latest 
nss_ldap version instead of the RedHat/Fedora bundled version and see what's 
changed.

LDAP client support for server lists/failover varies a lot.  Several client 
apps don't implement it at all.  So depending on what apps you need to 
support, it often makes more sense to provide redundancy at the server 
(e.g., with a load balancer).
