It depends. The FreeIPA SSO is Kerberos-based so you'd need to provide 
access to your KDC for this to work. If we're talking external portal 
then you may not want to expose your KDC.

It also requires some configuration. Your browser has to be configured 
to do Negotiate auth against a given domain.  It will also need to trust 
the IPA CA (and since CAS seems at least partially SSL-based you already 
handle this).

I don't know much about CAS other than what I just read on their web 
site but it looks like they handle redirecting when you aren't 
authenticated, seemingly allowing a nice way to mix protected and 
unprotected data. I think you'd have to do much of this configuration 
yourself in Apache. Probably not a huge amount of work though.

So it is basically whatever mod_auth_kerb provides.
