[jira] [Commented] (ACCUMULO-1028) Distinguish the user principal
from the authentication token
[ https://issues.apache.org/jira/browse/ACCUMULO-1028?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13569692#comment-13569692 ]
John Vines commented on ACCUMULO-1028:
--------------------------------------
While I agree with the user principal being extracted from the token, I think it's best to push any issues of token serialization outside of the client APIs, as well as keeping token deserialization in the Authenticator implementer.

> The user principal is something that uniquely identifies a user. An authentication token is the item that authenticates the user principal, may be temporal, and may vary. It is not clear from the implementation of ACCUMULO-259 that these are separate things, and I think it would benefit the API to distinguish them.
> It could also simplify the API, for users transitioning from the old authentication stuff to the new authentication stuff, because there would be a one-to-one mapping with the username/password with which they are familiar:
> {code:java}
> public Connector getConnector(String username, byte[] password);
> {code}
> becomes
> {code:java}
> public <T extends AuthToken> Connector getConnector(Principal userPrincipal, T authToken);
> {code}
