The line in question is:
return getattr(self, args[0])()
If args[0] is "login", then getattr(self, args[0]) will refer to the
gluon.tools.Auth.login method. The additional set of parentheses at the end
of the line indicate that method is actually being called, and its result
is being returned. So, ultimately, the login method is simply being called,
which you can find here:
