So the webserver does not know what his correct host name is or some
of te hostnames you mentioned, and generates an ACS URL in the
authentication request to the IdP that does not match the hostname
you're trying to access? (Note that you could easily check this
yourself by checking what's inside the autnRequest, e.g. with Mozilla
Firefox and Olav's "SAML Tracer" extension).

Then either using 'UseCanonicalName Off' or configuing a seperate
vhost for each hostname in httpd.conf and setting 'UseCanonicalName
On' in each (the latter being preferable), as well as adding all ACS
URL for each vhost/hostname in the entity's metadata this should work,
