[jira] [Created] (KNOX-28) Support federation/SSO using external tokens

Kevin Minder created KNOX-28:

             Summary: Support federation/SSO using external tokens
                 Key: KNOX-28
                 URL: https://issues.apache.org/jira/browse/KNOX-28
             Project: Apache Knox
          Issue Type: New Feature
            Reporter: Kevin Minder
            Assignee: Kevin Minder


During our discussions with a customer they expressed requirements that the gateway and ultimately Hadoop proper accept externally generated authentication tokens. There are really two possible models here.
1. The gateway accepts external tokens (e.g. SAML, JWT, SWT), extracts the principal and passes that downstream via either pseudo auth mechanism or creation of hadoop.auth tokens.
2. The gateway is transparent and passes these external tokens through to the downstream services where they will perform the required verification. This model provides better security but will require changes to all downstream Hadoop services.
