ERROR_DS_MISSING_EXPECTED_ATT
An expected attribute is missing.
ERROR_DS_MISSING_EXPECTED_ATT is Win32 error 8411 (0x000020DB) in Active Directory Domain Services (AD DS).
What to verify
Verify whether the target object contains the schema-defined attribute or constructed data that the directory operation expects. Check object DN and class, missing attribute name, and schema definition and mustContain rules.
Likely causes
- the object is incomplete or damaged.
- replication delivered inconsistent state.
- a migration or unsupported edit removed required data.
- the caller targeted the wrong object class.
Troubleshooting steps
- Collect object DN and class.
- Record missing attribute name.
Handling, retry, and recovery
Verify object class and replication, restore the attribute through supported management or recreate the damaged object when documented.

Example
