[sudo-users] sudoers config issues

[Loris.Serena at pfpc.ie]

Guys, 

I'd like to get a few users to be able to run some informix commands via 
sudo as the informix user.
Here are the relevant lines in the sudoers file:


# User alias specification
User_Alias      BKUP_ADMIN      = user1,user2,user3

# Cmnd alias specification
Cmnd_Alias      IMPR_BACKUP     = /opt/image/informix/informix/bin/onstat 
-l, \
 /opt/image/informix/informix/bin/ontape -c, \
                                  /opt/image/informix/informix/bin/ontape 
-r, \
                                  /opt/image/informix/informix/bin/ontape 
-s, \
                                  /opt/image/informix/informix/bin/onmode 
-ky, \
                                  /opt/image/informix/informix/bin/onstat 
-d

# User privilege specification
BKUP_ADMIN      ALL     =  (informix) NOPASSWD: IMPR_BACKUP



$ su - user2
bash-2.03$ sudo -l
User user2 may run the following commands on this host:
    (informix) NOPASSWD: /opt/image/informix/informix/bin/onstat -l, 
/opt/image/informix/informix/bin/ontape -c, 
/opt/image/informix/informix/bin/ontape -r, 
/opt/image/informix/informix/bin/ontape -s, 
/opt/image/informix/informix/bin/onmode -ky, 
/opt/image/informix/informix/bin/onstat -d


Now, I have two issues:

1. the NOPASSWD option doesn't seem to be working.
    Where do I have to specify it in order to have it work for all the 
commands in the IMPR_BACKUP Cmnd_Alias?

bash-2.03$ sudo /opt/image/informix/informix/bin/onstat -l
Password:

2. Even when I do provide the password, the command fails with the 
following message:

bash-2.03$ sudo /opt/image/informix/informix/bin/onstat -l
Password:
Sorry, user user2 is not allowed to execute 
'/opt/image/informix/informix/bin/onstat -l' as root on server1.
bash-2.03$


Can anyone see what I've done wrong here?

Thanks in advance for your help.
