Subject [jira] [Created] (HADOOP-12481) JWTRedirectAuthenticationHandler doesn't Retain Original Query String
Date Thu, 15 Oct 2015 16:40:05 GMT
Larry McCay created HADOOP-12481:

             Summary: JWTRedirectAuthenticationHandler doesn't Retain Original Query String
                 Key: HADOOP-12481
                 URL: https://issues.apache.org/jira/browse/HADOOP-12481
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
            Reporter: Larry McCay
            Assignee: Larry McCay
             Fix For: 2.8.0

Extend AltKerberosAuthenticationHandler to provide WebSSO flow for UIs.

The actual authentication is done by some external service that the handler will redirect
to when there is no hadoop.auth cookie and no JWT token found in the incoming request.

Using JWT provides a number of benefits:

* It is not tied to any specific authentication mechanism - so buys us many SSO integrations
* It is cryptographically verifiable for determining whether it can be trusted
* Checking for expiration allows for a limited lifetime and window for compromised use

This will introduce the use of nimbus-jose-jwt library for processing, validating and parsing
JWT tokens.
