Yes, group membership it set at login time. Running ksh as a login shell is not the same as actually logging in with a new session. > What is it that I have to do to have the membership updated, i.e., how > can I open e.g. a terminal in the running environment that would see my > new groups? You need to login in again. Logging in via ssh, a virtual console, X11 or running su will set the groups list. Setting groups is a privileged operation so simply starting a new shell or opening a new xterm is not sufficient. - todd
