Title
Active Roles: “Registration failed due to duplicate AD LDS directory partition DN” when registering multiple AD LDS instances -
Description
Registration failed due to duplicate AD LDS directory partition DN error when trying to add a second AD LDS instance from a different server.
-
Cause
This issue occurs when two or more AD LDS instances being registered in Active Roles share the same distinguished name (DN) for their directory partitions (for example,
DN=Company).Active Roles requires each managed directory partition to have a unique DN to correctly identify and manage directory objects. When duplicate DNs are detected, Active Roles cannot differentiate between objects across instances, and therefore registration fails.
-
Resolution
WORKAROUND
None.
This behavior is by design. The uniqueness check ensures consistency and prevents potential conflicts or data integrity issues within Active Roles.
