2. `id_token` claims: When the role policy is not configured, MinIO looks for a specific claim in the `id_token` (JWT) returned by the OpenID provider in the STS request. The default claim is `policy` and can be overridden by the `claim_name` configuration parameter or the `MINIO_IDENTITY_OPENID_CLAIM_NAME` environment variable. The claim value can be a string (comma-separated list) or an array of IAM access policy names defined...
