[jira] [Created] (DIRAPI-473) authenticated flag set before client-side SASL verification completes

Emmanuel Lécharny created DIRAPI-473:
----------------------------------------

             Summary: authenticated flag set before client-side SASL verification completes
                 Key: DIRAPI-473
                 URL: https://issues.apache.org/jira/browse/DIRAPI-473
             Project: Directory Client API
          Issue Type: Bug
    Affects Versions: 2.1.8
            Reporter: Emmanuel Lécharny
             Fix For: 2.1.9


An application performs a *GSSAPI* bind with mutual _auth_ against a spoofed/*MITM*'d server on a plaintext channel; the attacker returns *SUCCESS* with a bogus final token.
_evaluateChallenge_ throws, the app logs the failure, but the shared connection still reports _isAuthenticated()==true_ — a pool validator keeps it alive and a later code path reuses the connection to the attacker's endpoint as if mutual _auth_ had succeeded.
