So far the conversion was in a very random place -
register_remote_user(). All other codepaths that use
login_or_register_remote_user() call it with the user's email address.
Making remote_user_sso convert remote_username to the email address
before calling login_or_register_remote_user makes this usage consistent
across the board.
finish_desktop_flow is called with the assumption that the request
successfully proved control over the user_profile and generates a
special link to log into the user_profile account. There's no reason to
pass the realm param, as user_profile.realm can be assumed.
In `auth.py` there are three `if` blocks for different backends
to redirect to config error page with similar code. It is better
handled with common code using `get_attr()` function on
constructed setting names.
Create a new page for desktop auth flow, in which
users can select one from going to the app or
continue the flow in the browser.

This makes it possible to create a Zulip account from the mobile or
desktop apps and have the end result be that the user is logged in on
their mobile device.
We may need small changes in the desktop and/or mobile apps to support
this.
Closes#10859.
validate_otp_params needs to be moved to backends.py, because as of this
commit it'll be used both there and in views.auth - and import from
views.auth to backends.py causes circular import issue.
The desktop otp flow (to be added in next commits) will want to generate
one-time tokens for the app that will allow it to obtain an
authenticated session. log_into_subdomain will be the endpoint to pass
the one-time token to. Currently it uses signed data as its input
"tokens", which is not compatible with the otp flow, which requires
simpler (and fixed-length) token. Thus the correct scheme to use is to
store the authenticated data in redis and return a token tied to the
data, which should be passed to the log_into_subdomain endpoint.
In this commit, we replace the "pass signed data around" scheme with the
redis scheme, because there's no point having both.
authenticate_remote_user already takes care of calling the authenticate
with the dummy backend. Also, return_data is not used and catching
DoesNotExist exception is not needed, as the dummy backend just returns
None if user isn't found.
In other places where we set request._email, we set it to the
delivery_email, as that's more informative in orgs with hidden email
settings, where user.email will be useless.
By adding some additional plumbing (through PreregistrationUser) of the
full_name and an additional full_name_validated option, we
pre-populate the Full Name field in the registration form when coming
through a social backend (google/github/saml/etc.) and potentially skip
the registration form (if the user would have nothing to do there other
than clicking the Confirm button) and just create the account and log
the user in.
The main purpose of this is to make that name change happen in
/server_settings. external_authentication_methods is a much better, more
descriptive name than social_backends from API perspective.
This legacy endpoint was designed for the original native Zulip mobile
apps, which were deprecated years ago in favor of the React Native
app.
It was replaced by /server_settings for active use years ago, so it's
safe to remove it now.
The url scheme is now /accounts/login/social/saml/{idp_name} to initiate
login using the IdP configured under "idp_name" name.
display_name and display_logo (the name and icon to show on the "Log in
with" button) can be customized by adding the apprioprate settings in
the configured IdP dictionaries.
There are a few outstanding issues that we expect to resolve beforce
including this in a release, but this is good checkpoint to merge.
This PR is a collaboration with Tim Abbott.
Fixes#716.
This replaces the two custom Google authentication backends originally
written in 2012 with using the shared python-social-auth codebase that
we already use for the GitHub authentication backend. These are:
* GoogleMobileOauth2Backend, the ancient code path for mobile
authentication last used by the EOL original Zulip Android app.
* The `finish_google_oauth2` code path in zerver/views/auth.py, which
was the webapp (and modern mobile app) Google authentication code
path.
This change doesn't fix any known bugs; its main benefit is that we
get to remove hundreds of lines of security-sensitive semi-duplicated
code, replacing it with a widely trusted, high quality third-party
library.
We had a report in the thread around
https://chat.zulip.org/#narrow/stream/31-production-help/topic/Apache-based.20SSO/near/741013
that confirmation links were taking the user to the /register form on
the Apache server, which of course doesn't work because the Apache
server architecture we have is intended to only serve a single
endpoint, /accounts/login/sso, and not any static assets (etc.).
This manifested as users getting a broke page with a bunch of JS
errors about missing static assets when trying to sign up for an
account. The right fix is to ensure that we serve these confirmation
links (and maybe in the future, redirects) to the nginx server.
This makes the implementation of `get_realm` consistent with its
declared return type of `Realm` rather than `Optional[Realm]`.
Fixes#12263.

Previously, we had some expensive-to-calculate keys in
zulip_default_context, especially around enabled authentication
backends, which in total were a significant contributor to the
performance of various logged-out pages. Now, these keys are only
computed for the login/registration pages where they are needed.
This is a moderate performance optimization for the loading time of
many logged-out pages.
Closes#11929.
