Description Tamás Németh 2009-04-09 10:33:39 UTC 
Version:            (using KDE 4.2.2)
OS:                Linux
Installed from:    SuSE RPMs

There are some newer ultravnc servers, with an active directory based authentication. When I connect to one of these servers with an ultravnc client, I need to type both an username and a password.

When I try to connect with the plain commandline tightvnc client, it looks like this:
tamas@milleniumfalcon:~> vncviewer -encodings tight -bgr233 -compresslevel 9 -quality 0 172.16.243.1
Connected to RFB server, using protocol version 3.3
Unknown security type from RFB server: -6


krdc, on the other hand, seems to do simply nothing, it doesn't crash, doesn't hang doesn't give any error message, it just shows a blue screen. Could you implement this type of authentication in krdc?

This has been fixed in libvncserver:

I just test krdc 25.08 with ultravnc 1.6.4 and MSLogonIIAuth (username/password) auth works fine.
