Or, just list all the ldap server host names instead of the single host
name (if you can't do load-balancing), and all programs using libldap
will fail over to each server in the list.
For example, for nss_ldap (which would imply this is the wrong list for
this question ...) you could have this in /etc/ldap.conf:
host slave1 slave2 master
