sudo question

[Soo-Hyun Choi]

Hi,

I have a question on operating 'sudo' features over a Ubuntu Breezy system.

What I would like to do is that a user (e.g., foo) could 'sudo' to
'www-data' which is apache2. This is because I would like the user
(foo) to do some webmaster task on a system level.

So, what I did is the following, but the user (foo) cannot sudo to 'www-data'.
What's wrong with that?

# This is '/etc/sudoers' file
# User alias specification
User_Alias      WWW = foo

# User privilege specification
root            ALL=(ALL) ALL

# Users in the WWW User_Alias may run any command as user www-data
# (which owns the web pages) or simply su to www-data.
WWW     www-data=(www-data) ALL, (root) /bin/su www-data


Thanks for your information.
