With previous configuration format rules were not ordered between groups and
thus not predictable. Also in some cases `any` must have been a higher
precedence than `groups`. Flattening the rules let the user apply whatever
policy he can think of.
When several rules match the (subject, domain, resource), the first one is
applied.
NOTE: This commit changed the format for declaring ACLs. Be sure to update
your configuration file before upgrading.
In order to redirect the user after authentication, Authelia uses
rd query parameter provided by the proxy. However an attacker could
use phishing to make the user be redirected to a bad domain. In order
to avoid the user to be redirected to a bad location, Authelia now
verifies the redirection URL is under the protected domain.
In order to simplify the deployment of Authelia for
testing, LDAP is now optional made optional thanks
to users database stored in a file. One can update
the file manually even while Authelia is running.
With this feature the minimal configuration requires
only two components: Authelia and nginx.
The users database is obviously made for development
environments only as it prevents Authelia to be scaled
to more than one instance.
Note: Configuration has been updated. Key `ldap` has
been nested in `authentication_backend`.
Before this patch, when Authelia started, if Mongo was not
up and running, Authelia failed to connect and never retried.
Now, everytime Authelia faces a broken connection, it tries
to reconnect during the next operation.
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.
Issuer is customizable in configuration so that a company can set its own name
or website. If not provided, default value is 'authelia.com'.
The username is used as label.
This URL is used when user access the authentication domain without providing
the 'redirect' query parameter. In that case, Authelia does not know
where to redirect the user.
If the parameter is defined, Authelia can redirect the user to a default page
when no redirect parameter is provided.
When user is already authenticated and tries to access the authentication
domain, the "already logged in" page is rendered and it now tells the user he
is to be redirected in few seconds and uses this URL to redirect.
This parameter is optional. If it is not provided, there is only a notification
message at the end of the authentication process, as before, and the user is
not redirected when visiting the authentication domain while already
authenticated.
This timeout will prevent an attacker from using a session that has been
inactive for too long.
This inactivity timeout combined with the timeout before expiration makes a
good combination of security mechanisms to prevent session theft.
If no activity timeout is provided, then the feature is disabled and only
session expiration remains as a protection.
