Sudo error "The path must be a full path to a file and cannot end with a trailing slash". (4256300)

Sudo error "The path must be a full path to a file and cannot end with a trailing slash".

What is the correct syntax in Authentication Services SUDO Group Policy Dialog  box to enable a user to execute all commands in a directory? According to the sudo documentation, you use a path ending with a '/', but the SUDO Rule removes the slash and displays the error: "The path must be a full path to a file and cannot end with a trailing slash". We need to specify ALL commands in the directory because some of them contain hundreds of commands.
