Maybe you could setup 'sudo' to do this?  sudo would let the user run
a command as another user, and lets you specify the arguments that can
or cannot be used with the command. It's also easy to write a wrapper
script to do the function you want and give sudo access to this
script.

This way, you do not need to change the permissions on any of the
files; they would only be owned by the 'admin' user, and in addition
you can be more specific in specifying what the other users are able
to do.
