A vulnerability was found in Samba where a delegated administrator with permission to create objects in Active Directory can write to all attributes of the newly created object, including security-sensitive attributes, even after the object's creation.

The retained significant rights of the delegated administrator may not be well understood, potentially leading to unintended privilege escalation or security risks.
