Did you remember to turn on multiuser and add the user?

>From the screen you are trying to share, it's something like

Ctl-A : multiuser on
Ctl-A : acladd whoever

Once you've sorted it and if you will be doing it again with the same
users, you can put the command sequence into .screenrc and it will be
automagicated for you.

Also, for multi-user operation I think screen has to be setuid, so

sudo chmod u+s `which screen`

And probably also the PID file - in /var/run/screen?

Regards, K.
