[Freeipa-users] LDAP - Load Balancer - SSL cert with SAN

[Michael Plemmons]

Maciej,
  Thank you for the information.  I am not terminating at a load balancer.
Originally, I was trying to use a Route53 DNS CNAME entry of
ipa.dev.crosschx.com but we found documentation that says the entry should
be an A record and not a CNAME.  I then created an A record in FreeIPA for
ipa.dev.crosschx.com and pointed the A record to the IP addresses of
ipa-master.dev.crosschx.com and ipa-replica.dev.crosschx.com.

  I guess using the phrase load balancer may be a poor choice here as I am
using FreeIPA DNS as a way to load balance the traffic.
