# Which Problems Are Solved
ZITADEL currently selects the instance context based on a HTTP header
(see https://github.com/zitadel/zitadel/issues/8279#issue-2399959845 and
checks it against the list of instance domains. Let's call it instance
or API domain.
For any context based URL (e.g. OAuth, OIDC, SAML endpoints, links in
emails, ...) the requested domain (instance domain) will be used. Let's
call it the public domain.
In cases of proxied setups, all exposed domains (public domains) require
the domain to be managed as instance domain.
This can either be done using the "ExternalDomain" in the runtime config
or via system API, which requires a validation through CustomerPortal on
zitadel.cloud.
# How the Problems Are Solved
- Two new headers / header list are added:
- `InstanceHostHeaders`: an ordered list (first sent wins), which will
be used to match the instance.
(For backward compatibility: the `HTTP1HostHeader`, `HTTP2HostHeader`
and `forwarded`, `x-forwarded-for`, `x-forwarded-host` are checked
afterwards as well)
- `PublicHostHeaders`: an ordered list (first sent wins), which will be
used as public host / domain. This will be checked against a list of
trusted domains on the instance.
- The middleware intercepts all requests to the API and passes a
`DomainCtx` object with the hosts and protocol into the context
(previously only a computed `origin` was passed)
- HTTP / GRPC server do not longer try to match the headers to instances
themself, but use the passed `http.DomainContext` in their interceptors.
- The `RequestedHost` and `RequestedDomain` from authz.Instance are
removed in favor of the `http.DomainContext`
- When authenticating to or signing out from Console UI, the current
`http.DomainContext(ctx).Origin` (already checked by instance
interceptor for validity) is used to compute and dynamically add a
`redirect_uri` and `post_logout_redirect_uri`.
- Gateway passes all configured host headers (previously only did
`x-zitadel-*`)
- Admin API allows to manage trusted domain

This reverts commit e126ccc9aa.
# Which Problems Are Solved
#8295 introduced the possibility to handle idps on a single callback,
but broke current setups.
# How the Problems Are Solved
- Revert the change until a proper solution is found. Revert is needed
as docs were also changed.
# Additional Changes
None.
# Additional Context
- relates to #8295
# Which Problems Are Solved
Both the login UI and the IdP intent flow have their own IdP callback
endpoints.
This makes configuration hard to impossible (e.g. Github only allows one
endpoint) for customers.
# How the Problems Are Solved
- The login UI prefixes the `state` parameter when creating an auth /
SAML request.
- All requests now use the `/idp/callback` or the corresponding
variation (e.g. SAML)
- On callback, the state, resp. its prefix is checked. In case of the
login UI prefix, the request will be forwarded to the existing login UI
handler without the prefix state.
Existing setups will therefore not be affected and also requests started
before this release can be handled without any impact.
- Console only lists the "new" endpoint(s). Any
`/login/externalidp/callback` is removed.
# Additional Changes
- Cleaned up some images from the IdP documentation.
- fix the error handling in `handleExternalNotFoundOptionCheck`
# Additional Context
- closes#8236
# Which Problems Are Solved
ZITADEL currently always uses
`urn:oasis:names:tc:SAML:2.0:nameid-format:persistent` in SAML requests,
relying on the IdP to respect that flag and always return a peristent
nameid in order to be able to map the external user with an existing
user (idp link) in ZITADEL.
In case the IdP however returns a
`urn:oasis:names:tc:SAML:2.0:nameid-format:transient` (transient)
nameid, the attribute will differ between each request and it will not
be possible to match existing users.
# How the Problems Are Solved
This PR adds the following two options on SAML IdP:
- **nameIDFormat**: allows to set the nameid-format used in the SAML
Request
- **transientMappingAttributeName**: allows to set an attribute name,
which will be used instead of the nameid itself in case the returned
nameid-format is transient
# Additional Changes
To reduce impact on current installations, the `idp_templates6_saml`
table is altered with the two added columns by a setup job. New
installations will automatically get the table with the two columns
directly.
All idp unit tests are updated to use `expectEventstore` instead of the
deprecated `eventstoreExpect`.
