Subject [jira] [Commented] (HADOOP-11717) Add Redirecting WebSSO behavior with JWT Token in Hadoop Auth
Date Tue, 07 Apr 2015 15:17:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14483341#comment-14483341
] 

Owen O'Malley commented on HADOOP-11717:
----------------------------------------

I think this is good to go. If we want to generalize it further when we have additional use
cases to support, we can do that. This just provides a plugin for web sso that is useful to
users that don't want to use spnego for web ui.

> 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.
