Linda, have you looked at the CAS-MFA work which you can find here:

  https://github.com/Unicon/cas-mfa

That has been funded work (by the MFA Cohortium) to expand on previous CAS/MFA 
work (for Evergreen State), and provide functionality for CAS similar to what 
the Multi-Context Broker (MCB) does for the Shibboleth IdP. (Of course, you 
have that at Alaska.) I.e. try to significantly lower the threshold of work it 
takes to integrate a particular MFA technology into CAS, and provide flexible 
ways to "trigger it" (by service, by individual, etc.) That work, and its 
documentation, is currently being vetted by the University of Utah. But 
additional "vetters" ;-) would be most welcome. It includes a connector for 
Duo, and a connector for Toopher has been discussed.

It would be a different conversation to consider having the CAS Server defer 
authentication to the Shib IdP, where the IdP has the MCB. Certainly one could 
look into the "install a Shib SP and use the "TrustedAuth" login handler' 
approach that was discussed in an email thread that contained the following:

 http://listserv.educause.edu/cgi-bin/wa.exe?A2=ind1304&L=IDM&D=0&P=14972

If you got the Shib SP to send the needed authentication context in the authn 
request, you could force it for a given service. But it wouldn't work as well 
if you wanted to require MFA by individual, because you'd already need 
username/password to happen before you could look up whether this person was 
required to do MFA. Then they'd have to redo it for the IdP. (Unless you get 
circular and have the IdP then defer to CAS for username/password, but trying 
to think thru whether that could work smoothly would make my head hurt. Would 
clearly need to delineate between services at the CAS Server so that when sent 
there from the IdP, you didn't try and start the MFA loop over again.)
