[sudo-users] allow user a to copy files as user b

[George Kahler]

Hi, I am trying to set up sudoers to allow the user "wouser" to copy
files into a directory owned by user yim and have the target files be
owned by user yim. The user "wouser" would execute:

sudo -u yim cp <some-file> /dira/dirb/<some-file>

I created:

User_Alias      YIM       = wouser
Cmnd_Alias      YIM_CMD   = /sbin/su yim cp * /dira/dirb/*
CP_YIM          ALL = NOPASSWD: YIM_CMD

but this is not working too well.

What did I screw up ? Can you pls suggest a fix for this ?

Thanks.
George
