             Summary: Pac4J OAuth/OpenID Principal Needs to be Configurable
                 Key: KNOX-1119
                 URL: https://issues.apache.org/jira/browse/KNOX-1119
             Project: Apache Knox
          Issue Type: Bug
            Reporter: Larry McCay
            Assignee: Larry McCay
             Fix For: 0.14.0


Currently, the Pac4JIdentityAdapter blindly accepts the subject of the returned UserProfile which isn't directly usable in the Hadoop operating environment. We need to be able to resolve it to an actual username.

It seems that we could take two different approaches for this. 

1. Add a param to the pac4j provider to indicate the UserProfile attribute to use as the PrimaryPrincipal
2. Add a new identity assertion provider that can decrypt the pac4jUserProfile cookie and extract the configured attribute.

I lean towards #1 above so that identity assertion providers could be used to munge the extracted attribute in interesting ways.

[~jleleu] - Am I missing anything that is already in place for this?
