Andy,

Off hand, here's what I'd think about:

1) Why are you restricting CAS usage to registered services?  If you want to 
let any service use CAS, would you be happier adding an http://** entry?  If 
you don't want to let any service use CAS, then is it okay to let anyone run a 
service on their localhost and use CAS?

2) localhost isn't going to work for getting PGTs, since the CAS server won't 
be able to address the service to do the callback request.  To the extent that 
this developer wants to mess with proxy tickets, merely registering "localhost" 
isn't going to meet his needs.

3) Would you rather meet this need by asking this developer to run a 
development CAS instance on his desktop?  You're probably not willing to 
release interesting attributes from your institutional CAS server to 
"localhost", so a naive localhost deployment of the CAS quick start .war might 
be functionally equivalent.

4) Would you rather meet this need by running a non-production development 
instance of the CAS server with a more permissive configuration, so as to not 
introduce this service registration to your production CAS server?


If it were me, if I weren't willing to register http://**, I wouldn't be 
willing to register http://localhost .  And if I were willing to register 
http://**, then I wouldn't have to register http://localhost. :)

Kind regards,

Andrew
