+
+    Specifies a period of time (in seconds) that a specific user should wait
+    for the next attempt after failed authentication.
+
+    With the configuration below, Tarantool refuses the authentication attempt if the previous
+    attempt was less than 5 seconds ago.

+
+.. _cfg_auth_retries:
+
+.. confval:: auth_retries
+
+    Since :doc:`3.0.0 </release/3.0.0>`.
+
+    Specify the maximum number of authentication retries allowed before ``auth_delay`` is enforced.
+    The default value is 0, which means ``auth_delay`` is enforced after the first failed authentication attempt.
+
+    The retry counter is reset after ``auth_delay`` seconds since the first failed attempt.
+    For example, if a client tries to authenticate fewer than ``auth_retries`` times within ``auth_delay`` seconds, no authentication delay is enforced.
+    The retry counter is also reset after any successful authentication attempt.

+
+.. confval:: auth_type
+
+    Since :doc:`2.11.0 </release/2.11.0>`.
+
+    Specify an authentication protocol:
+
+    - 'chap-sha1': use the `CHAP <https://en.wikipedia.org/wiki/Challenge-Handshake_Authentication_Protocol>`_ protocol to authenticate users with ``SHA-1`` hashing applied to :ref:`passwords <authentication-passwords>`.
+    - 'pap-sha256': use `PAP <https://en.wikipedia.org/wiki/Password_Authentication_Protocol>`_ authentication with the ``SHA256`` hashing algorithm.
+
+    For new users, the :doc:`box.schema.user.create </reference/reference_lua/box_schema/user_create>` method
+    will generate authentication data using ``PAP-SHA256``.
+    For existing users, you need to reset a password using
+    :doc:`box.schema.user.passwd </reference/reference_lua/box_schema/user_passwd>`
+    to use the new authentication protocol.

+    Since :doc:`2.11.0 </release/2.11.0>`.
+
+    Specifies the maximum period of time (in days) a user can use the same password.
+    When this period ends, a user gets the "Password expired" error on a login attempt.
+    To restore access for such users, use :doc:`box.schema.user.passwd </reference/reference_lua/box_schema/user_passwd>`.
+
+    .. note::
+
+        The default 0 value means that a password never expires.
+
+    The example below shows how to set a maximum password age to 365 days.

+
+    Specifies the number of unique new user passwords before an old password can be reused.
+
+    In the example below, a new password should differ from the last three passwords.
+
+    .. code-block:: lua
+
+        box.cfg{ password_history_length = 3 }
+
+    | Type: integer
+    | Default: 0
+    | Environment variable: TT_PASSWORD_HISTORY_LENGTH
+    | Dynamic: yes
+
+    .. note::
+        Tarantool uses the ``auth_history`` field in the
+        :doc:`box.space._user </reference/reference_lua/box_space/_user>`
+        system space to store user passwords.

+.. confval:: wal_ext

+
+    (**Enterprise Edition only**) Allows you to add auxiliary information to each :ref:`write-ahead log <internals-wal>` record.
+    For example, you can enable storing an old and new tuple for each CRUD operation performed.
+    This information might be helpful for implementing a CDC (Change Data Capture) utility that transforms a data replication stream.
+
+    You can enable storing old and new tuples as follows:
+
+    *   Set the ``old`` and ``new`` options to ``true`` to store old and new tuples in a write-ahead log for all spaces.
+
+        ..  code-block:: lua
+
+            box.cfg {
+                wal_ext = { old = true, new = true }
+            }
+
+    *   To adjust these options for specific spaces, use the ``spaces`` option.
+
+        ..  code-block:: lua
+
+            box.cfg {
+                wal_ext = {

+                }
+            }
+
+
+        The configuration for specific spaces has priority over the global configuration,
+        so only new tuples are added to the log for ``space1`` and only old tuples for ``space2``.
+
+    Note that records with additional fields are :ref:`replicated <replication-architecture>` as follows:
+
+    *   If a replica doesn't support the extended format configured on a master, auxiliary fields are skipped.
+    *   If a replica and master have different configurations for WAL records, a master's configuration is ignored.
