SEC_E_INVALIDOBJECT
Meaning
Windows documents SEC_E_INVALIDOBJECT as “Object is invalid or unknown to the provider”. In this case, the protected object named in a security operation is invalid or unknown to the provider.
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.
Diagnostic sequence
- Identify the exact failing stage: the protected object named in a security operation is invalid or unknown to the provider.
Conditions that specifically lead to it
- Cause 1: the object identifier is malformed.
- Cause 2: the object was deleted or moved.
- Cause 3: an identifier from another provider or catalog was reused.
Evidence to collect
- Evidence 1: object type and full provider-scoped identifier.
- Evidence 2: existence lookup in the current data source.
- Evidence 3: provider and catalog identity that issued the object ID.
Corrective actions
- Action 1: resolve the object in the target namespace before editing security.
- Action 2: refresh identifiers after moves or schema deployment.
- Action 3: keep object IDs scoped to their owning provider.
Retry and recovery
Retry rule: retry after selecting an existing valid protected object.
Do not turn it into an unbounded retry loop. Preserve cancellation and use a fresh provider object when the failed call may have left local state ambiguous.
Difference from nearby HRESULT values
SEC_E_INVALIDACCESSENTRY concerns an individual permission entry, while SEC_E_INVALIDOBJECT concerns the protected resource.
Practical scenario
An ACL deployment targets a table ID from a staging catalog in production; resolving the production object prevents it. Keeping it with the method and object state makes this scenario diagnosable instead of reducing it to “database error”.
Operational dashboards should group by provider version, interface, method and normalized failure stage. A telemetry event must not expose passwords, tokens, full connection strings, unrestricted command text or raw row contents.
