 In case you run HTTPS in your local development environment, you might have a self-signed certificate. The Minio client by default verifies the TLS certificates, so would fail in this case. You can set `MINIO_DISABLE_CERT_CHECKS` to `true` to avoid this. Note: This setting only works if you also set `DEBUG` to `true` as well.
 
-## Client tokens
-
-If you want to use additional services that need to talk to caluma (e.g. [caluma-interval](https://github.com/projectcaluma/caluma-interval)), you need to have an additional OIDC-client with the `token_introspection` scope key.
-
-Following environment variables need to be set for caluma:
-
-* `OIDC_INTROSPECT_ENDPOINT`: introspect endpoint from the OIDC-provider
-* `OIDC_INTROSPECT_CLIENT_ID`: ID of the OIDC-client
-* `OIDC_INTROSPECT_CLIENT_SECRET`: Secret of the OIDC-client
-
-Some OIDC implementations (e.g. keycloak), allow for querying the `userinfo` endpoint with a client token. In that case the `introspection` endpoint is never called.
-
-The attribute `claims_source` on `OIDCUser` instances indicates the source of the claims.

 ## uWSGI defaults
 
 We are using the sane uWSGI-defaults researched by [bloomberg](https://www.techatbloomberg.com/blog/configuring-uwsgi-production-deployment/?sf104898833=1). You can override the defaults using environment variables.
