We will show how this can be done using case studies. It's only when we start to talk about federated identity that Shibboleth needs to come into the picture. We will look at federated identity and its unique requirements later using a specific case study. aspx 50 CAS Server Configuration and the “Two-Layer Protocol Architecture” Here are some tips for setting up CAS as your SSO server. Tip 1: Cater for high availability of the IAM solution IAM can become the single point of failure for all your applications unless you take steps to ensure its availability.
It must not be conflated with a more global identity for that user. Even the user's login ID on the SSO server is not their identity, even though this is the identifier that grants them access to a multitude of systems. Any systemspecific identifier is limiting because its scope is restricted. 11 The “IMA” part of LIMA stands for “Identity Management Architecture” of course, but you can choose to interpret the “L” as either “Low-cost”, “Lightweight” or “Loosely-coupled”, depending on whether your interest is economy, agility or architecture for its own sake.
The SP sends the ST handle to the IdP to validate it. In CAS, this is a direct HTTP call (not redirected through the browser since the RA is not yet trusted at this point). The IdP uses the ST handle to retrieve the ST from its Ticket Registry and validate it. The ST does not need to be held in the Ticket Registry for more than a few seconds, because the verification request from the SP typically comes in almost immediately after the IdP sends the RA the redirect request containing the ST handle.
