             Summary: Distinguish the user principal from the authentication token
                 Key: ACCUMULO-1028
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1028
             Project: Accumulo
          Issue Type: Sub-task
            Reporter: Christopher Tubbs


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}
