# Which Problems Are Solved
Currently if a user signs in using an IdP, once they sign out of
Zitadel, the corresponding IdP session is not terminated. This can be
the desired behavior. In some cases, e.g. when using a shared computer
it results in a potential security risk, since a follower user might be
able to sign in as the previous using the still open IdP session.
# How the Problems Are Solved
- Admins can enabled a federated logout option on SAML IdPs through the
Admin and Management APIs.
- During the termination of a login V1 session using OIDC end_session
endpoint, Zitadel will check if an IdP was used to authenticate that
session.
- In case there was a SAML IdP used with Federated Logout enabled, it
will intercept the logout process, store the information into the shared
cache and redirect to the federated logout endpoint in the V1 login.
- The V1 login federated logout endpoint checks every request on an
existing cache entry. On success it will create a SAML logout request
for the used IdP and either redirect or POST to the configured SLO
endpoint. The cache entry is updated with a `redirected` state.
- A SLO endpoint is added to the `/idp` handlers, which will handle the
SAML logout responses. At the moment it will check again for an existing
federated logout entry (with state `redirected`) in the cache. On
success, the user is redirected to the initially provided
`post_logout_redirect_uri` from the end_session request.

# Which Problems Are Solved
Some OAuth2 and OIDC providers require the use of PKCE for all their
clients. While ZITADEL already recommended the same for its clients, it
did not yet support the option on the IdP configuration.
# How the Problems Are Solved
- A new boolean `use_pkce` is added to the add/update generic OAuth/OIDC
endpoints.
- A new checkbox is added to the generic OAuth and OIDC provider
templates.
- The `rp.WithPKCE` option is added to the provider if the use of PKCE
has been set.
- The `rp.WithCodeChallenge` and `rp.WithCodeVerifier` options are added
to the OIDC/Auth BeginAuth and CodeExchange function.
- Store verifier or any other persistent argument in the intent or auth
request.
- Create corresponding session object before creating the intent, to be
able to store the information.
- (refactored session structs to use a constructor for unified creation
and better overview of actual usage)
Here's a screenshot showing the URI including the PKCE params:

# Additional Changes
None.
# Additional Context
- Closes#6449
- This PR replaces the existing PR (#8228) of @doncicuto. The base he
did was cherry picked. Thank you very much for that!
