It works, but the Red Hat tools don't create the optimal configuration
files. The following works in our environment (two LDAP servers, TLS
required). I set the various timelimit values low to facilitate a
fairly robust failover:
# failover doesn't seem to work work using the newer, and
# recommended, 'uri' directive.
host ldap1.you.com ldap2.you.com
# encrypt queries over the wire; our servers require it
# set time limits fairly low to get benefit of failover
