    bug 1068674

    Redo part of bp/sql-identiy-pam that was accidently undone by bug 968519.

    We encapsulated the call to utils.check_password with a local method,
    _check_password, to make it easier to subclass Identity. This allows us
    to use a different password checker without having to replace the entire
    authenticate method in our code. The fix for 968519 accidently removed
    the call to the local method. *This* fix puts that call back in.

    Updating comment because Jenkins failed due to build timeout in
    unrelated test.
