ERROR_DS_RESERVED_LINK_ID
The proposed linked-attribute identifier is in a reserved range
The linkID field marks linked attributes. Microsoft documents even values as forward links and odd values as backward links, and MS-ADTS applies additional consistency and uniqueness rules to nonzero link IDs. This result means the proposed schema extension selected an identifier that Active Directory reserves rather than one available for the custom definition.
Do not search for a free value by incrementing the number manually. Linked attributes are paired and their identifiers encode the forward/back-link relationship. Use the schema-extension procedure and identifier allocation method intended for custom attributes. If the LDIF came from a vendor, compare it with the supported product version instead of locally renumbering the link and silently breaking the paired attribute.
What to inspect
- Inspect the proposed
linkIDand determine whether the attribute is a forward or back link. - Verify the paired linked-attribute definition and its even or odd relationship.
- Use a supported allocation strategy rather than choosing an arbitrary numeric ID.
