Doesn't work, but it's better: the link appears even if the user is
anonymous, but if he clicks on the link then the authentication dialog box
opens. What I want is for the link to not appear at all, if possible.

the permissions on "my_method" are normal, except View which is only
allowed to roles Manager and Member, and not acquired.

Zope version is 2.3.1b2
