Francesco La Spina created GUACAMOLE-247:
--------------------------------------------
Summary: Guacamole shows 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: 0.9.11-incubating, 0.9.9
Environment: Default VNC server of Ubuntu 14.04 LTE (Desktop Sharing)
configured with a password
Reporter: Francesco La Spina
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.
