I believe this completes the project of ensuring that our recent work
on limiting what characters can appears in users' full names covers
the entire codebase.
In case realms have subdomains and the user hasn't been populated
yet in the Django User model, `ZulipLDAPAuthBackend` should not
rely on user's email domain to determine in which realm it should
be created in.
Fixes: #2227.
This makes it possible to configure only certain authentication
methods to be enabled on a per-realm basis.
Note that the authentication_methods_dict function (which checks what
backends are supported on the realm) requires an in function import
due to a circular dependency.
The actual logic is that if the user already exists than the
function should return a False and if the user does not exist
the function should first create the user and return True.
This improves Google and JWT auth as well as the registration
codepath to log something if the wrong subdomain is encountered.
Ideally, we'd have tests for these, and code to make the Google and JWT
auth cases show a clear error message.
This adds support for running a Zulip production server with each
realm on its own unique subdomain, e.g. https://realm_name.example.com.
This patch includes a ton of important features:
* Configuring the Zulip sesion middleware to issue cookier correctly
for the subdomains case.
* Throwing an error if the user tries to visit an invalid subdomain.
* Runs a portion of the Casper tests with REALMS_HAVE_SUBDOMAINS
enabled to test the subdomain signup process.
* Updating our integrations documentation to refer to the current subdomain.
* Enforces that users can only login to the subdomain of their realm
(but does not restrict the API; that will be tightened in a future commit).
Note that toggling settings.REALMS_HAVE_SUBDOMAINS on a live server is
not supported without manual intervention (the main problem will be
adding "subdomain" values for all the existing realms).
[substantially modified by tabbott as part of merging]
The recent changes to api_fetch_api_key to receive detailed data via
the "return_data" object did not properly update the LDAP backend to
accept that argument, causing mobile password authentication to not
work with the LDAP backend.
Previously, api_fetch_api_key would not give clear error messages if
password auth was disabled or the user's realm had been deactivated;
additionally, the account disabled error stopped triggering when we
moved the active account check into the auth decorators.
The security model for deactivated users (and users in deactivated
realms) being unable to access the service is intended to work via two
mechanisms:
* All active user sessions are deleted, and all login code paths
(where a user could get a new session) check whether the user (or
realm) is inactive before authorizing the request, preventing the
user from accessing the website and AJAX endpoints.
* All API code paths (which don't require a session) check whether the
user (and realm) are active.
However, this security model was not implemented correctly. In
particular, the check for whether a user has an active account in the
login process was done inside the login form's validators, which meant
that authentication mechanisms that did not use the login form
(e.g. Google and REMOTE_USER auth) could succeed in granting a session
even with an inactive account. The Zulip homepage would still fail to
load because the code for / includes an API call to Tornado authorized
by the user's token that would fail, but this mechanism could allow an
inactive user to access realm data or users to access data in a
deactivated realm.
This fixes the issue by adding explicit checks for inactive users and
inactive realms in all authentication backends (even those that were
already protected by the login form validator).
Mirror dummy users are already inactive, so we can remove the explicit
code around mirror dummy users.
The following commits add a complete set of tests for Zulip's inactive
user and realm security model.
Previously these users' names were being set to 1-element lists
containing the name, not the names themselves. This bug caused
existing users to have their people module state (e.g. @-mentions,
etc.) to break whenever a new user joined.
Fixes#222.
This addresses a few issues:
* The LDAP authentication integration now creates an account a new
Zulip account if the user authenticated correctly but didn't have a
Zulip account.
* The previous code didn't correctly disable the LDAP group
permissions functionality. We're not using groups support from the
Django LDAP extension and not doing so can cause errors trying to
fetch data from LDAP.
Huge thanks to @toaomatis for the initial implementation of this.
Fixes#72.
