Examples of org.subethamail.smtp.AuthenticationHandler.auth()

org.subethamail.smtp.AuthenticationHandler.auth()

Initially called using an input string in the RFC2554 form: "AUTH [initial-response]".
This method must provide the correct reply (by filling the response parameter) at each clientInput.

Depending on the authentication mechanism, the handshaking process may require many request-response passes. This method will return true only when the authentication process is finished
@return true if the authentication process is finished, false otherwise. @param clientInput The client's input. @param response a buffer filled with your response to the client input. @param ctx the connection context filled with the credential of the user if authentication succeeds. @throws org.subethamail.smtp.RejectException if authentication fails.

    try
    {
      // The authentication process may require a series of challenge-responses
      CRLFTerminatedReader reader = sess.getReader();


      String response = authHandler.auth(commandString);
      if (response != null)
      {
        // challenge-response iteration
        sess.sendResponse(response);
      }

          sess.sendResponse("501 Authentication canceled by client.");
          return;
        }
        else
        {
          response = authHandler.auth(clientInput);
          if (response != null)
          {
            // challenge-response iteration
            sess.sendResponse(response);
          }
