I have sudo set up for a shell script as follows on "hostname" (sudo -l output):

(suser) NOPASSWD: /path/script*

sudoers content is:

myuser ALL=(suser) NOPASSWD: /path/script* 

this works fine, so I can run the following, logged in locally on hostname, without need for password:

sudo -u suser /path/script

however, when I use ssh (with keys set up, so no password require) to login and run, as follows:

ssh hostname sudo -u suser /path/script 

I get prompted for a password, and when the password is entered I get:

Sorry, user myuser is not allowed to execute '/path/script' as suser on hostname

Why?

NB the following does not prompt for password at any point:

$ ssh hostname 
$ sudo -u suser /path/script
