Feature Proposal: Add some optional verbiage to the Access Denied message.

Motivation

We occasionally get the complaint that we don't allow edit on our System web. Also if we add restrictions to the Extensions, Download or other webs, it would be nice to explain why the web is restricted and how to obtain access.

Description and Documentation

We could do this a couple of ways.

• Create a WebRestrictions topic that describes reasons for any restrictions or
• Add an optional "ACLDescription" section to the WebPreferences topic.

And, to the access_denied template, add:

%INCLUDE{"WebPreferences,WebRestrictions" section="ACLDescription" warn="off"}%

We can add this to foswiki.org via a skin override, but it might be useful to others. This is more friendly than the "contact the webmaster" message.

Examples

In WebPreferences:

%STARTSECTION{"ACLDescription"}%
The System web on Foswiki.org is under Source Revision Control in
[[https://github.com/foswiki/distro][Github]].  You can propose changes by
[[Tasks/WebHome][Creating a task]].
%ENDSECTION{}%

Discussion

By setting include as %INCLUDE{"WebPreferences,WebRestrictions" section="ACLDescription" warn="off"}% Then a site that has completely view restricted a web can create a WebRestrictions topic for the message.

For now on foswiki.org, we can override this with the "fo" skin, which currently only adds the dismissable broadcast message. So no need to push this into 2.1.3

Done. Implemented on foswiki.org with a template override. messages.fo.tmpl
