[HECnet] Proxy to VMS?

I've run into a glitch with the map maker, which wants to make NICE connections to other nodes without authentication information. Depending on the OS, there is a notion of "default account" or "proxy", and I expected that to work when I send the connect request off without any username/password content. Apparently that's wrong for VMS, and I very vaguely remember this but not what to do about it. On VMS, how can you set up a network object to allow access without a password? If you do this, what is required in the connect request coming in? paul
