CAS OIDC: Configure different scope with different claims

[Devendra Sisodia]

Hello all,

I have configured CAS 5.3.6 with protocol OpenId Connect protocol for authentication. 

Issue 1:

Each scope should map to at least one or more claims. Right now it doesn’t matter which scope is chosen, always same set of claims is returned. Even if you provide no claims at all it still works, but should result in an error.

Issue 2: 

https://cas.example.org:8443/sso/oidc/.well-known/  => "id_token_signing_alg_values_supported":["none","RS256"],

alg for signing jwt returns both valid value and "none". How to avoid "none" ?

cas.properties: 

#OIDC

cas.authn.oidc.scopes=openid,profile,email,roles

cas.authn.oidc.claims = sub,email,givenName,isImpersonating, impersonator, firstName, lastName, roles, name

cas.authn.oidc.userDefinedScopes.profile=isImpersonating, impersonator, firstName, lastName, roles

cas.authn.oidc.userDefinedScopes.email=email

cas.authn.oidc.userDefinedScopes.roles=roles

cas.authn.oidc.issuer=http://cas.example.org:8443/cas/oidc

# Map predefined OIDC claims to our principal (user) attributes

cas.authn.oidc.claimsMap.givenName=firstName

cas.authn.oidc.claimsMap.lastName=lastName

cas.authn.oidc.claimsMap.mail=email

cas.authn.oidc.claimsMap.authorites=roles

cas.authn.oidc.claimsMap.name=name
