[jira] [Closed] (GUACAMOLE-247) Guacamole shows generic connection
error when a user connects to a VNC server without providing the password
[ https://issues.apache.org/jira/browse/GUACAMOLE-247?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nick Couchman closed GUACAMOLE-247.
-----------------------------------
Resolution: Fixed
As noted by [~user12319273], this issue is resolved in 1.3.0 by the support for parameter prompting, which will automatically prompt the user for a password (or a username and password) if required but missing.

> 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.
