"su" another user

I want to let a user A to use "su" to login to another user - user B where user A is null password, i tried to modify the file /etc/group and add user A to the wheel statement , but it still can't run su to login as user B , what is wrong in my system ? thx

What command are you using? As far as I know, user Bob can su to user Fred simply by doing 'su Fred' if he knows the password. Either messing with /etc/group is unnecessary or you're trying something more complicated that I'm not familiar with.

If you are logged as root, all you have to do is to type

# su NEW_USER

and you'll "be" that user...

if you're a normal user, just type

$su NEW_USER
password:

and you are in.

Yeah - if there's no password you should just be able to 'su B' and then hit 'enter' and you should be in. If that's not working, I don't know what the problem is. Maybe check /etc/passwd and make sure user B does in fact exist.

thx all reply , my problem is the user B is null password , so it should not to pop the password prompt , it seems the system don't allow user A to use "su" function . thx
