Hi Akbar, thanks! I'll document the current mod_authn_webid responses
to your rough list inline below.

no HTTP connection => no HTTP response status code

Not considered. Is this a failed GET sub-request of the WebID URI? If
so, this should be 502.

My only use of 403 is in mod_authz_webid (the RDF authorization/ACL
module).  At the very least, a more specific HTTP response body should
be returned from the various cases for 401 to differentiate them. I
had this on my TODO but will now hold it until this discussion

Best regards,
