    Fix parameters for Kerberos Auth Plugin

    The auth plugin was not loading when called from the CLI due to the
    mismatch of variable argument parameter calling convention. This was
    due in part to not specfying the parameters properly in the plugin, and
    also due to extending from the wrong base class.

    Closes-Bug: #1622079
