[Gambas-user] Program to use different group rights

[Rolf-Werner Eilert]

Good idea, Lee, but now I found that this will work only in a real 
shell, interactively. If I want to use it from a GUI program written in 
Gambas, I would at least have to offer a shell where the user can type 
in the password.

Is there really no chance for a test which runs completely in background 
other than using PAM libraries?

Regards
Rolf
