#### Description When `RESTSessionCatalog` is configured with a client_credentials, initSession() exchanges that credential for token, which becomes the `Authorization: Bearer ...` header on the catalog session. If a `SessionContext` also carries a credential (the pattern used by Trino when `iceberg.rest-catalog.session=NONE`) the first catalog operation triggers `contextualSession()` -> `fromCredential()`, which inherits the catalog parent session headers and forwards existing `Authorization` header alongside `client_id+client_secret` in body to the authorization server. Some OAuth2 authorization servers (in particular Okta) rejects such requests for token which contains both `Authorization: Bearer abcs` header and `client_id+client_secret` key pair (please see example how to check it directly on Okta). This PR is a proposition of filtering out `Authorization` header from headers inherited from parent session for token call in client credentials flow. To not break any existing use case scenario the filtering is hidden behind `skip-inherited-auth-header-in-token-request` feature flag passed as config property to `RESTSessionCatalog`. #### Reproduction of behavior directly on Okta ```bash CLIENT_ID="<CLIENT_ID>" CLIENT_SECRET="<CLIENT_SECRET>" OKTA_TOKEN_URL="<https://...okta.com/oauth2/.../v1/token>" OKTA_SCOPE="datacatalog" # successful request ACCESS_TOKEN=$(curl -X POST "$OKTA_TOKEN_URL" \ --header "Accept: application/json" \ --header "Content-Type: application/x-www-form-urlencoded" \ --header "X-Client-Version: Apache Iceberg 1.10.1-e.1 (commit 57448704eb9967abee52da13672326592e9ebe25)" \ --data "grant_type=client_credentials" \ --data "client_id=$CLIENT_ID" \ --data "client_secret=$CLIENT_SECRET" \ --data "scope=$OKTA_SCOPE" | jq -r '.access_token') # results: 200 + {"token_type":"Bearer","expires_in":3600,"access_token":"...","scope":"datacatalog"} # subsequent request which inherit Authorization header from session curl -X POST "$OKTA_TOKEN_URL" \ --header "Authorization: Bearer $ACCESS_TOKEN" \ --header "Accept: application/json" \ --header "Content-Type: application/x-www-form-urlencoded" \ --header "X-Client-Version: Apache Iceberg 1.10.1-e.1 (commit 57448704eb9967abee52da13672326592e9ebe25)" \ --data "grant_type=client_credentials" \ --data "client_id=$CLIENT_ID" \ --data "client_secret=$CLIENT_SECRET" \ --data "scope=$OKTA_SCOPE" # results: # 401 + {"errorCode":"invalid_client","errorSummary":"No client credentials found.","errorLink":"invalid_client","errorId":"...","errorCauses":[]} ``` -- This is an automated message from the Apache Git Service.
