The most common security query asks whether the current user has a
given permission. For example, suppose your application allows
some users to upload files. This action may be protected by the
"Add Documents, Images, and Files" standard Zope permission. You
can test to see if the current user has this permission in DTML::
'Add Documents, Images, and Files', this())">

How is this security check performed in a page template? I checked several options and came up with:
<span tal:condition="python:user.has_role('Author')"> ...
which works, but not in combination with SlaveUserFolders. I defined a user in a parent folder with the role
"Member" and assigned the role "Author" within the subfolder using a SlaveUserFolder. It still shows the role
"Member", but not "Author".
With the wrong role, the permission check will using user.has_permission not work either.
