Multiple virtual hosts on SP 3

The redirect pattern sounds like a load balancer in round robin configuration (switching among hosts on each request).
If this is the case, set the load balancer to sticky sessions.

Figured I would start here. I'm following the UW[1] and Oxford[2]

instructions for setting up a single SP with multiple vhosts. I don't

need the vhosts to be treated differently, it's even the same app, but

they are on vastly different domains, which might what is causing the


The generated metadata has both domains in the generated metadata, of

course with the same single entityID. I am using CAS 5.1 as my IdP.

1) I hit

2) Sent to CAS

3) Auth

4) CAS sends me back to

5) Shib SP validates data and gives me a cookie for

6) SP redirects me to

7) My SP cookie was issued for domain1, so it isn't being sent to

domain2, so goto #2

In general, how does the IdP know where to send the user back to if

there are multiple listed domains? It's possible the version of CAS I am

on doesn't support this. But I'm wondering in general how this is

supposed to work, or if I'm missing something other than just having two

EndpointBase values.

 From where I'm at, it looks like the best option for me is different

entityIDs via the entityIDSelf param in HTTPD. That is certainly doable,

I just want to make sure that I'm not missing something.
