[Fwd: Quota function]

Dear All,

Is there config sample for using Quota function ( cmd of quota and 
edquota ) ?

For user's bash_profile :

PATH=$PATH:/sbin:/usr/sbin:/usr/local/bin

For running with visudo :

HOST = NOPASSWD:    /usr/sbin/edquota, /usr/bin/quota

For home directory :
[manager@xxx ~]$ ls -l -h /home/aquota.*
-rw-r--r-- 1 root root 10K Nov  4 23:32 /home/aquota.group
-rw-r--r-- 1 root root 10K Nov  4 23:32 /home/aquota.user
[manager@xxx ~]$

BUT the result :

[manager@xxxx ~]$ sudo quota -v edward
Password:

[manager@xxxx ~]$ sudo edquota -p qwe -u zxc
Password:

NEED password ???

So, what misstake I had ?
Many thank for your help !

Edward.
