It's possible that this won't work with some versions of the
third-party backend, but tabbott has tested carefully that it does
work correctly with the Apache basic auth backend in our test
environment.
In this commit we start to support redirects to urls supplied as a
'next' param for the following two backends:
* GoogleOAuth2 based backend.
* GitHubAuthBackend.
This is necessary for mobile apps to do the right thing when only
RemoteUserBackend is enabled, namely, directly redirect to the
third-party SSO auth site as soon as the user enters the server URL
(no need to display a login form, since it'll be useless).
Previously, we used to raise an exception if the direct dev login code
path was attempted when:
* we were running under production environment.
* dev. login was not enabled.
Now we redirect to an error page and give an explanatory message to the
user.
Fixes#8249.
When the answer is False, this will allow the mobile app to show a
warning that push notifications will not work and the server admin
should set them up.
Based partly on Kunal's PR #7810. Provides the necessary backend API
for zulip/zulip-mobile#1507.
We keep having to change the same thing in three places here; and also
the duplicates have accumulated unnecessary variation that makes it
hard to see what's actually supposed to be different and not different
in the three cases.
For example, this means that if a user already has an account on one
realm and they try to make an account on another by hitting "Sign in
with Google" (rather than following the little "Register" link to a
"Sign up with Google" button instead), they'll get to make an account
instead of getting an error.
Until very recently, if the user existed on another realm, any attempt
to register with that email address had to fail in the end, so this
logic gave the user a useful error message early. We introduced it in
c23aaa178 "GitHub: Show error on login page for wrong subdomain"
back in 2016-10 for that purpose. No longer! We now support reusing
an email on multiple realms, so we let the user proceed instead.
This function's interface is kind of confusing, but I believe when its
callers use it properly, `invalid_subdomain` should only ever be true
when `user_profile` is None -- in which case the revised
`invalid_subdomain` condition in this commit can never actually fire,
and the `invalid_subdomain` parameter no longer has any effect. (At
least some unit tests call this function improperly in that respect.)
I've kept this commit to a minimal change, but it would be a good
followup to go through the call sites, verify that, eliminate the use
of `invalid_subdomain`, then remove it from the function entirely.
This completes the last commit's work to fix CVE-2017-0910, applying
to any invite links already created before the fix was deployed. With
this change, all new-user registrations must match an explicit realm
in the PreregistrationUser row, except when creating a new realm.
[greg: rewrote commit message]
This deletes the old mock-covered test for this, which was mostly
useless. We have a much less messy test, which we extend to provide
the same test coverage the old one did.
While the result was the same before, this makes it more obvious.
This code path was only required because we had remote_user set as a
positional argument here, and thus we'd be running this auth backend's
code when actually using another auth backend (due to how Django auth
backends are selected based on argument signature).
The cookie mechanism only works when passing the login token to a
subdomain. URLs work across domains, which is why they're the
standard transport for SSO on the web. Switch to URLs.
Tweaked by tabbott to add a test for an expired token.
This makes the tests a little cleaner in itself, and also prepares
them to adjust with less churn when we change how
redirect_and_log_into_subdomain passes the signed token.
If an organization doesn't have the EmailAuthBackend (which allows
password auth) enabled, then our password reset form doesn't do
anything, so we should hide it in the UI.
Most of the paths leading through this except clause were cut in
73e8bba37 "ldap auth: Reassure django_auth_ldap". The remaining one
had no test coverage -- the case that leads to it had a narrow unit
test, but no test had the exception actually propagate here. As a
result, the clause was mistakenly cut, in commit
8d7f961a6 "LDAP: Remove now-impossible except clause.", which could
lead to an uncaught exception in production.
Restore the except clause, and add a test for it.
This makes GoogleSubdomainLoginTest consistently access subdomains the
standard way, replacing the original hacky approach it had that
predated the library.
The plan is to have everything expect subdomains, so it makes sense to
move these tests to the subdomains-only test class and style.
Most of the remaining GoogleLoginTest tests are now either duplicates
or basic API-level tests where subdomains are irrelevant.
This commit enables user to authenticate with any attribute set in
AUTH_LDAP_USER_SEARCH given that LDAP_EMAIL_ATTR is set to an email
attributes in the ldap server. Thus email and username can be
completely unrelated.
With some tweaks by tabbott to squash in the documentation and make it
work on older servers.
Previously, we didn't pass customized HTTP_HOST headers when making
network requests. As we move towards a world where everything is on a
subdomain, we'll want to start doing that.
The vast majority of our test code is written to interact with the
default "zulip" realm, which has a subdomain of "zulip". While
probably longer-term, we'll wish this was the root domain, for now, we
need to make our HTTP requests match what is expected by the test
code.
This commit almost certainly introduces some weird bugs where code was
expecting a different subdomain but the tests doesn't fail yet. It's
not clear how to find all of these, but I've done some grepping.
Previously, Zulip's server logs would not show which user or client
was involved in login or user registration actions, which made
debugging more annoying than it needed to be.
This should significantly improve the user experience for new users
signing up with GitHub/Google auth. It comes complete with tests for
the various cases. Further work may be needed for LDAP to not prompt
for a password, however.
Fixes#886.
This allows us to go to Registration form directly. This behaviour is
similar to what we follow in GitHub oAuth. Before this, in registration
flow if an account was not found, user was asked if they wanted to go to
registration flow. This confirmation behavior is followed for login
oauth path.
This error isn't saying that any kind of authentication or
authorization failed -- it's just a validation error like
any other validation error in the values the user is asking to
set. The thought of authentication comes into it only because
the setting happens to be *about* authentication.
Fix the error to look like the other validation errors around it,
rather than give a 403 HTTP status code and a "reason" field that
mimics the "reason" fields in `api_fetch_api_key`.
Currently we only pass headers in the first client_get call but
sometimes the effective request which reaches the view is through
a later call to the client_get in this function. Due to which
headers are not passed.
These handlers will kick into action when is_signup is False. In case
the account exists, the user will be logged in, otherwise, user will
be asked if they want to proceed to registration.
This fixes most cases where we were assigning a user to
the var email and then calling get_user_profile_by_email with
that var.
(This was fixed mostly with a script.)
The example_user() function is specifically designed for
AARON, hamlet, cordelia, and friends, and it allows a concise
way of using their built-in user profiles. Eventually, the
widespread use of example_user() should help us with refactorings
such as moving the tests users out of the "zulip.com" realm
and deprecating get_user_profile_by_email.
Specifically, this makes easily available to the desktop and mobile
apps data on the server's configuration, including important details
like the realm icon, name, and description.
It deprecates /api/v1/get_auth_backends.
