The environment at the moment is a selection of windows and Linux (RHEL 4/5 and SLES 10/11) whereby VNC access to the windows boxes works using ultravnc and providing a username/password combination to authenticate.
What is desirable is to use VNC to gain access to the Linux servers with authentication (before the console is displayed) being handled via a username/password combination.
I know that using VNC it is possible to handle this with a generic password or no password at all.
What is the best solution in this case? Is it possible to configure VNC access as desired?
Also beneficial would be having authentication done via pam so that pam_access and other restrictions are used.
