 This guide will explain setup, configuration and usage of the SCS Domain Manager standard.
 
-### Warning regarding the exposure of domain names
-
-Due to architectural limitations currently existing in OpenStack Keystone, assigning the `manager` role to users while the configuration of the SCS Domain Manager standard has been applied will **enable them to see the IDs and names of all existing domains**.
-This includes domains other than their own, meaning that other tenant's identities might be exposed depending on the relation between them and the name of their domain.
-CSPs aiming to appoint Domain Manager users must be aware of this limitation and should exclusively **use pseudonymized domain names across the whole infrastructure**.
-If CSPs strictly follow the [SCS naming conventions](https://github.com/SovereignCloudStack/standards/blob/main/Standards/scs-0301-v1-naming-conventions.md) for domains this is already addressed.
-If this is not feasible for the CSP, they may opt to refrain from making use of the Domain Manager functionality at all, i.e. never assign the `manager` role to tenant users.
-
 :::info
 
-This architectural limitation will be fixed in upcoming OpenStack and SCS releases.

-See [https://bugs.launchpad.net/keystone/+bug/2041611](https://bugs.launchpad.net/keystone/+bug/2041611)
+The Domain Manager functionality, formerly exclusive to the corresponding SCS standard, will be natively integrated into OpenStack starting with release 2024.2 ("Dalmatian").
+When using an OpenStack release equal to 2024.2 or later, you can omit the instructions for Keystone API policy adjustments.
