-
-Authentication allows users to log in, but authorization determines what they can do once authenticated.
-
-Redpanda Console supports role-based access control (RBAC) through two modes:
-
-- **User impersonation enabled**: Redpanda enforces authorization using its internal ACL and RBAC rules. The identity of the logged-in user is forwarded to the Kafka API, Admin API, and Schema Registry.
-- **User impersonation disabled**: Redpanda Console enforces access using `roleBindings` in the Redpanda Console configuration file. All API requests are made using a static service account.

-Even with a valid login, users must still be granted permissions in Redpanda or in `roleBindings` to access resources. A Redpanda Console role (such as Admin) does not automatically grant permissions in Redpanda.

 All APIs must be accessible using a superuser principal. If the service account lacks superuser status, Redpanda Console may not be able to fetch cluster status, access the Admin API, or interact with the Schema Registry.
 
+=== Transform identities with principal mappings
+
+If you use OIDC login, the identity in the JWT token is extracted using a JSONPath expression. By default, this expression is `$.sub`, which means the value of the `sub` claim is used as the username. You can override this expression using the `principalMapping` option to transform or extract a different claim to match the `name` values in your `roleBindings` configuration.
+
+To keep authorization consistent between Console and Redpanda, set `principalMapping` to match Redpanda's cluster configuration value for xref:reference:properties/cluster-properties.adoc#oidc_principal_mapping[`oidc_principal_mapping`].

+This example:

+* Uses a regular expression to capture the username part
+* Replaces the value with the captured group `$1`
+* Converts the result to lowercase (`L` modifier)
+
+As a result, the user identity becomes `matt` when the email is `matt@example.com`.
+
+You can then define role bindings like this:
+
+[,yaml]
+----
+authorization:
+  roleBindings:
+    - roleName: admin
+      users:
+        - loginType: oidc
+          name: matt
+----
+
+==== Match syntax and modifiers
+
+The `principalMapping` syntax uses this format:
+
+----
+<jsonpath>/<regex>/<replacement>/<modifiers>
+----
+
+* `jsonpath`: Path to the claim field in the token (such as `$.email`)
+* `regex`: A regular expression to extract part of the claim
+* `replacement`: A replacement string using a captured group (such as `$1`)
+* `modifiers`: Optional flags, such as:
+  - `L` — convert to lowercase
+  - `U` — convert to uppercase
+
+[NOTE]
+====
+If `principalMapping` is not set, Redpanda Console defaults to using the `sub` claim as the user identity.
+====
+
 == Multiple roles and duplicate bindings
 
 You can assign multiple roles to the same user through role bindings. In this case, the user receives the union of all permissions associated with those roles.
