CAS 4 Goals, Design, and Features Marvin Addison Middleware Services Virginia Tech May 24, 2011

CAS 4 Goals, Design, and Features6 Goals Multiprotocol support by design CAS protocols SAML 1.1 and SAML 2 OpenID Support important/emerging use cases User messaging (e.g. password expiration) Multi-factor authentication Federation Add extension points with richer APIs

CAS 4 Goals, Design, and Features7 Change Hurts

CAS 4 Goals, Design, and Features8 Component Name Changes CAS 3CAS 4 TicketGrantingTicketSession (implied)Access ServiceTicketTokenServiceAccessRequest TicketRegistrySessionStorage

CAS 4 Goals, Design, and Features9 Name Change Rationale Concise, accurate names clarify the API Names distill common features of all (planned) protocols Avoid overloading names (e.g. Ticket) Name implied but important concepts (e.g. Access)

CAS 4 Goals, Design, and Features10 Richer Component Interfaces Core layers remain same Authentication Ticket (Session) management Service management Layers exchange *Request/*Response messages Factories help tame dependencies

CAS 4 Goals, Design, and Features11 Login Example Credential s SW F POST CntrAuthSvc LoginRequest LoginResponse AuthenticationManager AuthenticationRequest AuthenticationResponse

CAS 4 Goals, Design, and Features12 What Can We Do With It?

CAS 4 Goals, Design, and Features13 Password Expiration Warnings Two key API components collaborate GeneralSecurityExceptionTranslator LoginResponse MicrosoftActiveDirectoryGeneralSecurityExceptio nTranslator translates LDAP exception for password expired into CredentialExpiredException LoginResponse#getGeneralSecurityExceptions() available to view layer for user display

CAS 4 Goals, Design, and Features14 Multifactor Authentication Key enablers are support for multiple credentials in LoginRequest and storage of multiple authn exeptions in LoginResponse The Map is fundamentally important for SWF processing and user interaction Details of user interaction (e.g. how to upgrade existing credential) not well understood

CAS 4 Goals, Design, and Features15 Work in Progress CAS 4 is undergoing active development We MUST get new APIs right Peer review and collaboration essential to success – is your use case covered? Feedback welcome on

You should use these at your own risk. Many are excellent clients, but may no longer be supported any more. Others are purely theoretical examples of of how a client would function.

19 CAS Clients – Incubating.NET CAS Client (almost official...) CASBar – Toolbar for Firefox 2 Official Clients Incubating Clients are new clients that are under development, and which may become official clients. They're up-and-coming clients that we're paying attention to, have petitioned the Steering Committee to become official clients, and often have active members on cas- user.

20 CAS Clients – Legacy Yale CAS Client Apache Module PAM PL/SQL Legacy Clients In many cases, no longer actively developed, but still function quite well (i.e. the PAM module). In other cases, they've been superseded by newer clients (i.e. The Jasig CAS Client for Java). You will still find many people on cas-user who are familiar with these modules, but many have migrated to the newer code.
