Adding users as vifp users

Is there a way to allow individual users to use vifp (fastpass).  When I add users and try to run commands under them I get the error "This is not the vifp user"

For audit reasons I want to have each admin log in as themselves and run commands and scripts but I don't see where I can do that.

Thanks!
