[wp-edu] Lots of domains, single sign-in

[Scot Hacker]

We have around 30 WordPress domains in a .edu environment and we need  
to get wp-admin behind https for all of them.  We can't get a separate  
IP for  each domain.

Using the university's CAS (central sign-in service) via a plugin  
would be an ideal solution, but we have many users with logins who are  
not part of the university. Facebook login would be another option,  
but this isn't ideal for various reasons.

The university network officials want us to find a way to redirect  
users to a single sign-in domain, then back to the domain they're  
logging into. My question is, how can this be done with WordPress?  
Does anyone have experience with this?

Thanks,
Scot
