Look at ipa-rewrite.conf in the IPA Apache config. It does rewriting to 
the real name of the IPA server when it was installed. You can try 
tweaking this to allow both names, or to just not do the rewriting.

You may have issues with Kerberos and SSL due to using a different name.

You definitely don't want to use IPA over an unsecure channel.
