Suse 9.3 Non root shutdown SOLUTION
Suse 9.3 by default install kdm as the initial windows manager. The configuration by default requires to be root to shutdown from the GUI.
Find the procedure bellow (please as I use French GUIs some translation might not match one to one the English GUI)
I provide the YAST version first and by direct access to config file in the second part. The secnd solution works beter if you need to do it remotly.
---------------- YAST ----------------
This can be changed from YAST.
select "Security and Users" (one before the last)
sub1 select "Security parameter" (last option)
Sub2a select "personal paramters" (last radio button)
Sub 2b leave unchanged "Paramters for root password"
Sub2c on the screen "startup parameters"
on the last item "stopdown kdm behaviour" select "all users" in replacement of "automatic".
Sub2d leave unchanged "login parameters" screen
Sub2e leave unchanged "add user" screen
Sub2f leave unchanged "various parameters" screen
cllick on "done" button.
==> You can now shutdown from the GUI without root password.
--------------- config files ----------------------------
# su to root
edit file /etc/sysconfig/displaymanager
change the paramter (on my system at line 54)
KDM_SHUTDOWN="all"
save your change
run the suse config script by typing
SuSEconfig
==> You can now shutdown from the GUI without root password.
