Chmod ug + s su
Then it should be OK.
Permission comparison:
Permission before modification:-rwxrwxrwx
Permission after modification:-rwsrwsrwx
Why should I grant su this file + s this permission?
The add s permission executes the program as the owner. This is why root can use su, but other users cannot.
