[Zope3-Users] Grant role top zope.anybody

[Florian Lindner]

Hello,
I've tried to grant a role to zope.anybody (any user that visits the site). 
Tried it this way:

    <grant
        role = "my.role"
        principal = "zope.anybody"
    />

But this gives a unknown principal id error, even though I have:

  <unauthenticatedPrincipal
    id="zope.anybody"
    title="Unauthenticated User" />

in my principal.zcml.

How to do it right?

Thanks,

Florian
