Hi Mike, Per our pervious email correspondence below, we successfully upgraded to the latest Apache Incubator version of Guacamole, and we’re now seeing the “Password authentication failed: Authentication failed (username/password)” message caught and logged at the guacd layer when a bad username and/or password is entered for a Linux SSH session, however, looks like the message is not being bubbled back up to the guac client view (the guac view turns black, and the user cannot interact with the connection).
From what I can tell, once a bad username/password is caught at the guacd layer, the connection to the VM is immediately disconnected, and the guac client layer receives a “User disconnected” message, and the socket to guacd is closed. The guac client layer does not receive the bad username/password message. Is there a way to show the bad username/password error on the guac client view, so that the user can re-enter his/her username and password, and not have to reconnect to the VM?

In our scenario, for connecting to Linux VM’s via Guacamole, we’re not passing usernames and/or password, and thus, Guacamole is prompting for username and password (which is exactly what we’re looking for :-), however, we noticed that if we pass a bad username/password, the Guacamole view does not provide an error message, and does not indicate that a bad username/password was provided, but rather, the view seems to hang, and the user cannot interact with the view. We’re wondering if this is a bug? Ideally, we were hoping that the view would indicate that a bad username/password was provided, and to please try again. Yes, this is a bug, but it should have been fixed recently: https://github.com/apache/incubator-guacamole-server/commit/7c2766b34bd10f0ae2dcd0b378696fb454498a76 If you can, please try building from git to see if the problem is resolved. For reference, the original report of this issue was GUAC-1381 [1], fixed while debugging changes for GUAC-1389 [2] (finalization of screen sharing support in the backend). The issue is not in the Apache JIRA as it was fixed before migration to Apache Incubator was completed. - Mike [1] https://glyptodon.org/jira/browse/GUAC-1381 [2] https://glyptodon.org/jira/browse/GUAC-1389
