Subject [jira] [Commented] (HADOOP-8779) Use tokens regardless of authentication type
Date Fri, 07 Sep 2012 23:37:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8779?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13451135#comment-13451135

Aaron T. Myers commented on HADOOP-8779:
----------------------------------------

I think it's a bit of a misrepresentation to say that tokens are only used for authorization.
Yes, they also carry information that can be used to authorize an otherwise authenticated
client, but in some cases they are also used for authentication itself, e.g. in the case of
BlockTokens.

> Security is a combination of authentication and authorization (tokens).  Authorization
may be granted independently of the authentication model.  Tokens should be used regardless
of simple or kerberos authentication.
