Bug Description

Binary package hint: vinagre

Remote Desktop Viewer (Vinagre) 2.28.1-0ubuntu1
Ubuntu 9.10 Karmic Koala

While trying to connect to a VNC server, the password field on the Authentication is required screen cannot accept more than 8 characters. A Windows Real VNC client can accept up to 9 characters on the password (I have not tested more).

The same 8 char limit is applied when a connection is configured through a SSH tunnel and vinagre asks for the SSH password to open the tunnel, however no such limit exists on the SSH passwords.

The VNC protocol limits passwords to 8 chars. This is the specification. Vinagre just follows the spec.

However I fixed the bug that limits SSH passwords length: http://git.gnome.org/browse/vinagre/commit/?id=e0721cd7c31291142117ec39da75d48ec4940db8

I appreciate that the "Standard" says 8 chars but when other implementations have increased the length presumably for security reasons it makes Vinagre unusable and I have to again boot into windows so I can use realVNC to be able to log into these servers.
