You need to add haproxy.example.com as a SAN of the IPA host, or
vice-versa.
Also, the service in the SAN must be "managed by" the host on which
the certificate is issued (i.e. the host in the CN). You can do
this in the web UI: Services > {service} > Hosts > Add. I do not
know of a way to do this via CLI - if someone knows a way please
shout out!
So if the IPA service is `HTTP/ipa.example.com' and load balancer
service `HTTP/haproxy.example.com' is managed by host
`ipa.example.com', you can run:
ipa-getcert request {nssdb-options} -n haproxy-cert \
-K HTTP/ipa.example.com \
-N CN=ipa.example.com \
-D haproxy.ipa.local
-K gives principal, -N gives DN and and -D gives dNSName SAN.
