[sudo-users] How do I use visudo to allow users to su another account?

[Matthew Barrett]

I have regular users who need to sudo to an account with web directory
access to update web sites. Some can "sudo - webuser" and enter their
password with no problem. One user could before and now have lost the
ability. I've taken over the responsibility and am not sure how to do
this. Any ideas would be appreciated?
