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.
