Bug ID: 435985
Summary: VNC via SSH tunnel always asks for password even
though public key authentication is set-up
Product: krdc
Version: 21.03.90
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Target Milestone: ---
SUMMARY
When connecting to a VNC server via SSH tunnel, KRDC always asks for password
authentication (PW auth is already discouraged and disabled by default in most
distros) even though I'm using public key authentication.
STEPS TO REPRODUCE
1. Create connection to an SSH server that has a running VNC server by enabling
SSH tunneling
2. Connect
OBSERVED RESULT
* A password popup appears
* Pressing okay with any password throws: "Error authenticating with password:
Access denied for 'password'. Authentication that can continue: publickey"
* Pressing cancel cancels the connection
EXPECTED RESULT
It should not ask for a password and continue if my publickey is authorized to
connect.
