Traefik handles auth forwarding but does not manage redirections like Nginx.
Therefore, Authelia must redirect the user and Traefik will forward this
request.
To support both Nginx and Traefik, /api/verify is now configurable with the
'redirect' get parameter. If the verification fails and 'redirect' is not
provided the response will be a 401 error as before.
If the parameter is provided and set to any URL, the response will be a
redirection (302) to this URL.
One can now access a service using the basic authorization mechanism. Note the
service must not be protected by 2 factors.
The Remote-User and Remote-Groups are forwarded from Authelia like any browser
authentication.
From this commit on, api endpoints reply with a 401 error code and non api
endpoints redirect to /error/40X.
This commit also fixes missing restrictions on /loggedin (the "already logged
in page). This was not a security issue, though.
The change also makes error pages automatically redirect the user after few
seconds based on the referrer or the default_redirection_url if provided in the
configuration.
Warning: The old /verify endpoint of the REST API has moved to /api/verify.
You will need to update your nginx configuration to take this change into
account.
These are 2 measures for improving security of cookies. One is used to
not send the cookie over HTTP (only HTTPS) and the other tells the browser to
disallow client-side code accessing the cookie.
One can now customize the default authentication method for all sub-domains,
i.e., either 'two_factor' or 'basic_auth' and define specific authentication
method per sub-domain.
For example, one can specify that every sub-domain must be authenticated with
two factor except one sub-domain that must be authenticated with basic auth.
ACLs can now be defined by subdomain AND resource using pattern matching
with regular expressions.
It allows a very fine-grained access control to backend resources.
[Note] For using example environmnent, user must update its /etc/hosts with
new subdomains updated in README.
Before this fix, the redirection URL was stored in the user session,
but this has a big drawback since user could open several pages in
browser and thus override the redirection URL leading the user to
be incorrectly redirected.
