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
