CAS 1 and CAS 2

[Andrew Ralph Feller, afelle1]

CAS 1: Basic authentication; user requests service directly and receives it
CAS 2: Proxy authentication; service requests another service on behalf of
user and receives it

An example where this is useful: your company / organization has a portal
that everyone logs in.  If you expect the portal to deliver your email for
you, then it is requesting your email on behalf of you.  If the email server
is CAS protected, then this would never work, so the portal must request
your email on your behalf.

I wouldn¹t say proxy authentication is for a portal environment; it is
useful whenever you want build some manner of web service.
