Michael Jumper updated GUACAMOLE-247:
-------------------------------------
Priority: Trivial (was: Major)
> Guacamole shows generic connection error when a user connects to a VNC server
> without providing the password
> ------------------------------------------------------------------------------------------------------------
>
> Key: GUACAMOLE-247
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-247
> Project: Guacamole
> Issue Type: Bug
> Components: VNC
> Affects Versions: 0.9.9, 0.9.11-incubating
> Environment: Default VNC server of Ubuntu 14.04 LTE (Desktop Sharing)
> configured with a password
> Reporter: Francesco La Spina
> Priority: Trivial
> Attachments: guacamole_vnc_no_psw_error.png
>
>
> If a VNC connection is configured without a password (e.g in
> user-mapping.xml) and the server requires it, Guacamole client shows an error
> connection message instead of a proper wrong/missing password message or an
> input field for the password.
