LDN - Luminis Developer Network

Maybe I am just getting greedy but.... if we have a workstation in our Windows Domain (Active Directory) and someone is logged into it is there possibly a way to have single sign on into Luminis? This works seemlessly when accessing other machines in the domain for stuff like file services and printer sharing. My guess is there would have to be some sort of Kerberos tie in into Luminis.

We are using Luminis 4.0.2.0 on a Red Hat box
