I'm afraid the command was working as expected.

% sudo chmod g+s $(which id) =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0=C2=A0

% id -g

0


% sudo chmod g-s $(which id)

% id -g=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 = =C2=A0 =C2=A0

100

Okay, no "nosuid" option in there, so that's also rule= d out.


As a test, set the setgid bit on the id binary like this:

sudo chmod g+s $(which id)

then, as a non-root user(!) run:

id -g

Make sure to disable the setgit bit again with:

sudo chmod g-s $(which id)


If the previous id -g call returned an effective group ID of 0, that means = that
setgid functionality should be working on your system. If it's not 0, t= he reason
for your problems are likely that setgid on files is not working correctly = on
your system.
