Hello,
I have 3 LDAP servers which I want HAproxy to loadbalance the connections among them.
Below is my configuration for haproxy.cfg.
I would be very grateful if you share your thoughts and comments.
Thank you for your attention.

global
# to have these messages end up in /var/log/haproxy.log you will
# need to:
#
# 1) configure syslog to accept network log events. This is done
# by adding the '-r' option to the SYSLOGD_OPTIONS in
# /etc/sysconfig/syslog
#
# 2) configure local2 events to go to the /var/log/haproxy.log
# file. A line like the following can be added to
# /etc/sysconfig/syslog
#
# local2.* /var/log/haproxy.log
#
# log 127.0.0.1 local2
log /dev/log local0
