Sudo command prompt for a password

in the /etc/sudoer file this line was added:

wtolentino ALL=(ORACLE) NOPASSWD: /bin/chmod

when i tried to run this command

sudo -u oracle /bin/chmod 775 /appshared/applications/lpa/executables/chrpt001.rep 

it prompts me for a password

for example:

$ pwd
/appshared/applications/lpa
$ ls -l
total 48
drwxrwxr-x    2 wtolenti staff          4096 Mar 02 12:46 doc
drwxrwxrwx    2 wtolenti staff         16384 Mar 13 10:11 executables
drwxrwxr-x    5 wtolenti staff          4096 Feb 16 08:37 source
$ cd executables
$ ls -l chrpt001.rep
-rw-r--r--    1 oracle   oinstall      98304 Mar 13 10:11 chrpt001.rep
$ sudo -u oracle /bin/chmod 775 /appshared/applications/lpa/executables/chrpt001.rep
Password:

the file is chrpt001.rdf is owned by oracle and i am attempting to change the permission using the sudo command.

please advise.

thank you.

Shouldn't that be /etc/sudoers ? And, unless the "Runas_Spec" ORACLE is a "User_Alias" for oracle , shouldn't it be lower case?

Also, make sure you're using visudo instead of trying to edit the config file directly.
