I haven't heard anyone mention SunRays on this list, so this might be a new topic
A SunRay is a thin client device made by Sun which connects to a Solaris or Linux server to receive (by tftp) it's operating system, IP address and general personality. My objective is to use the SunRay clients in Kiosk mode ie they start an X session as a unique generic user on the Linux (Etch in my case) Server, which runs a RDP session to a Windows Terminal Server. . . . but X is starting with gdmgreeter, requiring Linux credentials. Once I've authenticated as glennc (or root) the Xsession runs as the generic user utk0, and the RDP client application runs. I'm looking for suggestions for removing the gdmgreeter login step. GC
