as per instructions regarding cas client, placed authorize tag above login page when user wants log in, instead redirected cas server login, , upon successful validation, "login" actionresult redirects user specific page.

    [authorize]     public actionresult login()     {         return redirecttoaction("index", "departments");     } 

i have tested cas implementation , can confirm works expected, lost in regards how go getting information cas server after validates user.

any appreciated, , if duplicate post apologize unable find of sort while searching myself.

it looks may matter of pulling value httpcontext.current.user.identity.name, should return value of cas username of authenticated user. there post on jasig-cas-user mailing list tipped me off this.

another mailing list post suggests other returned information may accessible through casauthentication.currentprincipal.assertion.attributes, isn't particularly well-documented on wiki.

the implication accessing data cas return demonstrated in example web application distributed code, isn't intuitive there , not documented anywhere else. (i installed using nuget, , missed out on sample application altogether. found question before found answer myself!)
