[cas-dev] DotNetCasClient, getting access to more service response properties

[Elijah W. Gagne]

Hi All,

 

I've modified DotNetCasClient so that User.Identity.Name is set cas:netid (custom property) instead of cas:user. This solved a problem for me because cas:user at Dartmouth is based on a person's name. As a result, if your name changed then an app based on DotNetCasClient would see you as a new user. cas:netid at Dartmouth is unique and guaranteed to never change for someone.

 

Now my updated version of DotNetCasClient sets User.Identity.Name from the cas:netid. This is great, except that there is additional data in the cas:serviceResponse that I'd like to utilize. For instance, I'd like to use cas:name. I tried out setting User.Identity.Name = cas:netid + "|" + cas:name. That worked well for gaining access to both the username and displayname for a person. However, because my app's UserProfile table is setup such that username = netid (not cas:netid + "|" + cas:name), the built in function Roles.IsUserInRole() function no longer works.

 

I could get the DisplayName of a person at logon time by doing an LDAP query, but that is ugly. Is there a simple way to get access to other cas:serviceResponse properties?

 

Thanks!

Yes, via CasAuthentication.CurrentPrincipal.Assertion.Attributes. [1,
2] I'm embarrassed that this is so poorly documented. We demonstrate
a number of features of the client in the ExampleWebApp distributed
with source, but that important feature is missing. I'd be happy to
work on adding a source example if you'd open a Jira issue and assign
to me.

Thanks,
M
