You can have multiple virtual hosts with the TLS endpoint being KC.  We do
ti with OpenUnison and apache lets you do it I think with TLS 1.2 and
apache 2.4 (I have a customer thats doing that right now so I know it
works).  So long as the cert has multiple Subject Alternative Names or is a
wildcard it should work.

OpenUnison originally took the "everything in a cookie" approach, the
cookie quickly got too big to be effective and we had to switch to
maintaining a backend session.

I know I've brought this up before, but I'd like to offer up OpenUnison as
a starting point: https://github.com/tremolosecurity/openunison.  OU
probably has 70%-80% of what you are looking for.  It already has the
reverse proxy code built in, written in Java, supports extensibility via
multiple mechanisms, an authorization subsystem that can easily be extended
to support an external az service and we have an extensible last mile
system for legacy apps that don't support openid connect for apache, .net
and Java.  We also have multiple production deployments (including public
safety applications).

>From a corporate standpoint we're already Red Hat partners at multiple
levels.  We're sponsoring Summit this year again and I'll be doing a
session on OpenShift identity management and compliance.
