We've decided to add a 'brand' field to help clients decide how to style the
buttons.
Also, fix up the allowed characters for idp_id, while I'm in the area.
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 request, we can fish the user id out of the session, and use it to look up the external id mappings, and hence pick an SSO provider for them.
* Implement CasHandler.handle_redirect_request
... to make it match OidcHandler and SamlHandler
* Clean up interface for OidcHandler.handle_redirect_request
Make it accept `client_redirect_url=None`.
* Clean up interface for `SamlHandler.handle_redirect_request`
... bring it into line with CAS and OIDC by making it take a Request parameter,
move the magic for `client_redirect_url` for UIA into the handler, and fix the
return type to be a `str` rather than a `bytes`.
* Define a common protocol for SSO auth provider impls
* Give SsoIdentityProvider an ID and register them
* Combine the SSO Redirect servlets
Now that the SsoHandler knows about the identity providers, we can combine the
various *RedirectServlets into a single implementation which delegates to the
right IdP.

The spec requires synapse to support `identifier` dicts for `m.login.password`
user-interactive auth, which it did not (instead, it required an undocumented
`user` parameter.)
To fix this properly, we need to pull the code that interprets `identifier`
into `AuthHandler.validate_login` so that it can be called from the UIA code.
Fixes#5665.
The main use case is to see how many requests are being made, and how
many are second/third/etc attempts. If there are large number of retries
then that likely indicates a delivery problem.
This converts a few more of our inline HTML templates to Jinja. This is somewhat part of #7280 and should make it a bit easier to customize these in the future.
The idea is that in future tokens will encode a mapping of instance to position. However, we don't want to include the full instance name in the string representation, so instead we'll have a mapping between instance name and an immutable integer ID in the DB that we can use instead. We'll then do the lookup when we serialize/deserialize the token (we could alternatively pass around an `Instance` type that includes both the name and ID, but that turns out to be a lot more invasive).
Broken in https://github.com/matrix-org/synapse/pull/8275 and has yet to be put in a release. Fixes https://github.com/matrix-org/synapse/issues/8418.
`next_link` is an optional parameter. However, we were checking whether the `next_link` param was valid, even if it wasn't provided. In that case, `next_link` was `None`, which would clearly not be a valid URL.
This would prevent password reset and other operations if `next_link` was not provided, and the `next_link_domain_whitelist` config option was set.
This endpoint should only deal with emails that have already been approved, and
are attached with user's account. There's no need to re-check them here.

This PR adds a confirmation step to resetting your user password between clicking the link in your email and your password actually being reset.
This is to better align our password reset flow with the industry standard of requiring a confirmation from the user after email validation.
This is a config option ported over from DINUM's Sydent: https://github.com/matrix-org/sydent/pull/285
They've switched to validating 3PIDs via Synapse rather than Sydent, and would like to retain this functionality.
This original purpose for this change is phishing prevention. This solution could also potentially be replaced by a similar one to https://github.com/matrix-org/synapse/pull/8004, but across all `*/submit_token` endpoint.
This option may still be useful to enterprise even with that safeguard in place though, if they want to be absolutely sure that their employees don't follow links to other domains.
