RE: DHCP and D4GL WTK Client

I can't think of anything that would help you prevent the prompt from appearing. Even though D4GL was supposed to give one the feeling that they're running a Windows app, the fact remains that it's requesting data and services from a UNIX box that's a stickler for authorization. From my testing, I discovered that if you add the user's PC hostname to your database/application server's hosts.equiv file, no matter what the user entered as the password, as long as the username was valid it would allow the login (the password field could even be blank!). So if you're willing to accept the risk (which you'd probably have to be since there's probably no solution that would allow your D4GL client to connect without authenticating itself as belonging to a proper UNIX user) then you could use the -u <username> flag in the D4GL shortcut so that the username will appear by default and then all they'll have to do is press the OK button. Another possible route to explore is the HTML client. I haven't looked at it nor have I seen one in action. Can anyone inform us about what the authorization for web-based D4GL clients is like?
