UI Auth via SSO: redirect the user to an appropriate SSO. #9081
Conversation
for clarity
... because we might not have it during later steps.
To avoid a situation where a user authenticated with one IdP, but that is no longer configured, check that the mappings are for known IdPs.
# we checked that the user had some remote identities before offering an SSO | ||
# flow, so either it's been deleted or the client has requested SSO despite | ||
# it not being offered. | ||
raise SynapseError(400, "User has no SSO identities") |

At this point in the flow should we be rendering JSON or HTML errors? (Should this use sso_handler.render_error
?)

good point.

that said... there are plenty of other places we are raising SynapseErrors in this method. Ideally they'd all be caught and sent to sso_handler.render_error
instead, and while we're at it I think start_sso_ui_auth
probably just wants to move into SsoHandler
, but that feels like a bigger refactor.

This theoretically isn't stable before Python 3.7. I suspect we don't care since they can use any identity.

If we have integrations with multiple identity providers, when the user does a UI Auth, we need to redirect them to the right one.
There are a few steps to this. First of all we actually need to store the userid of the user we are trying to validate in the UIA session, since the
/auth/sso/fallback/web
request is unauthenticated.Then, once we get the
/auth/sso/fallback/web
