This completes a major redesign of the Zulip login and registration
pages, making them look much more slick and modern.
Major features include:
* Display of the realm name, description and icon on the login page
and registration pages in the subdomains case.
* Much slicker looking buttons and input fields.
* A new overall style for the exterior of these portico pages.
This commit makes sure that GitHubAuthBackend will only authenticate
using its own authenticate method. This is done by adding a new
Python Social Auth strategy which instead of calling authenticate
method of Django, calls the authenticate of the backend directly.
The problem this commit solves is that while authenticating through
GitHub backend, we were ending up getting authenticated through
ZulipDummyBackend. This might happen because the default strategy used
by Python Social Auth calls the authenticate method of Django which
iterates over all the backends and tries the authenticate methods
which match with the function arguments. The new strategy this commit
adds calls the authenticate method of GitHub backend directly which
makes sense because we already know that we want to authenticate with
GithHub.
The actual problem of why we are ending up on ZulipDummyBackend is
still a mystery because the function arguments passed to its
authenticate method are different. It shouldn't be called.
Django tries to authenticate against all backends one by one.
The authenticate() function of GitHub backend used to take
*args and **kwargs arguments due to which it could be called
against any set of arguments. Django uses arguments to
differentiate authenticate() methods.
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.
If you're using e.g. our Jabber<=>Zulip mirroring capability along
with the RemoteUser SSO integration, previously it would fail if a
user with a corresponding dummy user tried to login/signup (since they
didn't have an account but one wouldn't be created because
ZulipRemoteUserBackend was reporting that an account already existed).

This change disabled password auth, but the UI still shows the login
form. I will remove that once we have the new hostname.

CUSTOMER16 wants their employee realm to:
* only use JWT logins
* have name changes be disabled (they want users' full names to be the
their CUSTOMER16 user name).
* not show the suggestion that users download the desktop app

This is used by the Android app to authenticate without prompting for a
password.
To do so, we implement a custom authentication backend that validates
the ID token provided by Google and then tries to see if we have a
corresponding UserProfile on file for them.
If the attestation is valid but the user is unregistered, we return that
fact by modifying a dictionary passed in as a parameter. We then return
the appropriate error message via the API.
This commit adds a dependency on the "googleapi" module. On Debian-based
systems with the Zulip APT repository:
sudo apt-get install python-googleapi
For OS X and other platforms:
pip install googleapi

If authoritative data is available from say the LDAP database, we now
ignore the POSTed user name, and don't offer it as a form field.
We fall back to giving the user a text field if they aren't in LDAP.
If users do not have any form fields to fill out, we simply bring them
to the app without the registration page, logging them in using a dummy
backend.

The latter doesn't depend on the former; we can still fill in your full
name even if you didn't authenticate via LDAP.
This commit requires django_auth_ldap to be installed. On Debian
systems, you can do so via APT:
sudo apt-get install python-django-auth-ldap
On OS X, use your favourite package manager. For pip, I believe this
will work:
pip install django_auth_ldap
django_auth_ldap depends on the "ldap" Python package, which should be
installed automatically on your system.

This includes a hack to preserve humbug/backends.py as a symlink, so
that we don't need to regenerate all our old sessions.
