sudeors file not affecting user privileges

[Aijaz Baig]

Hello,

I would like 'normal users' to be able to issue the shutdown command. For
that reason I modified the 'sudoers' file and I uncommented the last line
which now reads:* *
*%users localhost=/sbin/shutdown -h now*

However that didn't work. Then I thought
maybe the users above refer to some user defined group called 'users. So I
first created a group called 'users' and added 'masud' (one of my users) to
that group. Still No luck..

Then I read a bit about how does one actually add stuff to that file and
added(appended) the following to the file:* masud ALL=/sbin/shutdown -h now*

Well..nothing yet..I always log in as as 'masud' and try to see if shutdown
works (by issuing *shutdown -h now* from his account) and I get
*/sbin/shutdown:
Permission denied
*
Well..How do I go about it...

Please do let me know.

Hope to hear from you soon,

Best Regards,
Aijaz Baig.
