[web2py] Re: Auth is now always a cas service

[Ross Peoples]

I am not that familiar with CAS, but it might be useful in some cases to 
know what groups the user is a member of in the remote web2py installation. 
For example, if there is an 'Administrators' group that should have access 
to everything, then you wouldn't have to set up groups and permissions for 
every single app that uses the remote Auth service.
