From 9c715a5f1981891815c124353ba15cf4d17bf9bb Mon Sep 17 00:00:00 2001 From: Richard van der Hoff <1389908+richvdh@users.noreply.github.com> Date: Mon, 1 Feb 2021 15:47:59 +0000 Subject: Fix SSO on workers (#9271) Fixes #8966. * Factor out build_synapse_client_resource_tree Start a function which will mount resources common to all workers. * Move sso init into build_synapse_client_resource_tree ... so that we don't have to do it for each worker * Fix SSO-login-via-a-worker Expose the SSO login endpoints on workers, like the documentation says. * Update workers config for new endpoints Add documentation for endpoints recently added (#8942, #9017, #9262) * remove submit_token from workers endpoints list this *doesn't* work on workers (yet). * changelog * Add a comment about the odd path for SAML2Resource --- changelog.d/9271.bugfix | 1 + docs/workers.md | 18 +++++----- synapse/app/generic_worker.py | 11 +++--- synapse/app/homeserver.py | 18 ++-------- synapse/rest/synapse/client/__init__.py | 49 +++++++++++++++++++++++++- synapse/storage/databases/main/registration.py | 40 ++++++++++----------- tests/rest/client/v1/test_login.py | 15 ++------ tests/rest/client/v2_alpha/test_auth.py | 6 ++-- 8 files changed, 93 insertions(+), 65 deletions(-) create mode 100644 changelog.d/9271.bugfix diff --git a/changelog.d/9271.bugfix b/changelog.d/9271.bugfix new file mode 100644 index 0000000000..ef30c6570f --- /dev/null +++ b/changelog.d/9271.bugfix @@ -0,0 +1 @@ +Fix single-sign-on when the endpoints are routed to synapse workers. diff --git a/docs/workers.md b/docs/workers.md index d01683681f..6b8887de36 100644 --- a/docs/workers.md +++ b/docs/workers.md @@ -225,7 +225,6 @@ expressions: ^/_matrix/client/(api/v1|r0|unstable)/joined_groups$ ^/_matrix/client/(api/v1|r0|unstable)/publicised_groups$ ^/_matrix/client/(api/v1|r0|unstable)/publicised_groups/ - ^/_synapse/client/password_reset/email/submit_token$ # Registration/login requests ^/_matrix/client/(api/v1|r0|unstable)/login$ @@ -256,25 +255,28 @@ Additionally, the following endpoints should be included if Synapse is configure to use SSO (you only need to include the ones for whichever SSO provider you're using): + # for all SSO providers + ^/_matrix/client/(api/v1|r0|unstable)/login/sso/redirect + ^/_synapse/client/pick_idp$ + ^/_synapse/client/pick_username + ^/_synapse/client/sso_register$ + # OpenID Connect requests. - ^/_matrix/client/(api/v1|r0|unstable)/login/sso/redirect$ ^/_synapse/oidc/callback$ # SAML requests. - ^/_matrix/client/(api/v1|r0|unstable)/login/sso/redirect$ ^/_matrix/saml2/authn_response$ # CAS requests. - ^/_matrix/client/(api/v1|r0|unstable)/login/(cas|sso)/redirect$ ^/_matrix/client/(api/v1|r0|unstable)/login/cas/ticket$ -Note that a HTTP listener with `client` and `federation` resources must be -configured in the `worker_listeners` option in the worker config. - -Ensure that all SSO logins go to a single process (usually the main process). +Ensure that all SSO logins go to a single process.
