SEC_E_NOOWNER
Meaning
Windows documents SEC_E_NOOWNER as “Object does not have an owner”. In this case, a security query expects an owner but the target object has no owner defined by the provider.
Evidence to collect
When recording diagnostic data involving SIDs, account names, groups, ACL contents and protected object identifiers, use types, lengths, hashes or redacted identifiers rather than secrets or complete business data.
- Evidence 1: object type and identifier.
- Evidence 2: provider owner/group response.
- Evidence 3: creation and ownership-change history.
Relevant contract
OLE DB security administration represents trustees, owners, groups, protected objects and access-entry lists as separate entities. A syntactically valid trustee can still be unknown to a provider, and an allowed permission set depends on the protected object type.
Investigation of this result should start with the provider security interface, effective data-source namespace and exact trustee or access-entry structure supplied.
Conditions that specifically lead to it
- Cause 1: the object type does not require ownership.
- Cause 2: the object was created without an owner.
- Cause 3: provider metadata is incomplete or ownership was removed.
Diagnostic sequence
- Identify the exact failing stage: a security query expects an owner but the target object has no owner defined by the provider.
Corrective actions
- Action 1: treat no owner as a distinct supported state where documented.
- Action 2: assign an owner through the provider interface when required.
- Action 3: repair provider metadata only with an authoritative ownership source.
Practical scenario
An audit exporter assumes every object has an owner; representing ownerless objects explicitly prevents repeated failures.
Retry and recovery
Retry rule: retry the owner-dependent operation after a valid owner has been assigned.
Difference from nearby HRESULT values
SEC_E_INVALIDOWNER rejects a supplied owner trustee, while SEC_E_NOOWNER reports that the object currently has none.
