DB_SEC_E_PERMISSIONDENIED

Permission denied

Exact value and interpretation

DB_SEC_E_PERMISSIONDENIED has the unsigned 32-bit value 2147749385 (0x80040E09) and the signed representation -2147217911. AllStat defines the result as “Permission denied”. In the concrete failure represented here, the data source recognizes the caller but denies the requested OLE DB operation.

The high bit is set for DB_SEC_E_PERMISSIONDENIED, so it is a failure HRESULT rather than a success or informational status. Its facility field is 4 (FACILITY_ITF) and its low code is 3593 (0x0E09). Those bit fields place DB_SEC_E_PERMISSIONDENIED in an interface-defined family, but they do not reveal the provider, object identity, method, rowset generation or command state that produced it.

Evidence to collect before changing the system

A useful DB_SEC_E_PERMISSIONDENIED record includes provider CLSID and version, process architecture, interface and method, COM apartment and thread, object correlation ID, transaction state, and the first preceding HRESULT. When DB_SEC_E_PERMISSIONDENIED involves credentials, access tokens, principal identifiers and protected data, record types, lengths, hashes or redacted identifiers instead of secrets or full business data.

  • Evidence 1 for DB_SEC_E_PERMISSIONDENIED: the authenticated principal and effective security context.
  • Evidence 2 for DB_SEC_E_PERMISSIONDENIED: the exact object, method and requested access mode.
  • Evidence 3 for DB_SEC_E_PERMISSIONDENIED: provider error records, server audit entries and policy decision details.

OLE DB contract boundary

DB_SEC_E_PERMISSIONDENIED must be interpreted against this contract: OLE DB security results depend on the identity actually presented to the provider and the authorization applied to the specific data source object, command, table or row; authentication and permission denial are distinct stages.

Start with the provider connection, effective principal and protected object or operation when investigating DB_SEC_E_PERMISSIONDENIED. Preserve DB_SEC_E_PERMISSIONDENIED before ADO, ATL, .NET, a database abstraction layer or an application exception replaces it with a generic message; the exact interface and method matter because one OLE DB object can expose several contracts with different preconditions.

Specific conditions that produce this result

  • Cause 1 for DB_SEC_E_PERMISSIONDENIED: the principal lacks table, column, procedure or object permission.
  • Cause 2 for DB_SEC_E_PERMISSIONDENIED: the connection is running under a different identity than expected.
  • Cause 3 for DB_SEC_E_PERMISSIONDENIED: row-level or provider policy denies the selected object or operation.

Diagnostic sequence

  1. Capture DB_SEC_E_PERMISSIONDENIED immediately at the native OLE DB return and obtain the current OLE DB error object before another COM call replaces thread error information.
  2. Identify the exact stage for DB_SEC_E_PERMISSIONDENIED: the data source recognizes the caller but denies the requested OLE DB operation.
  3. For DB_SEC_E_PERMISSIONDENIED, compare the live command, rowset, accessor or schema state with the metadata and properties actually granted by the provider.
  4. For DB_SEC_E_PERMISSIONDENIED, inspect per-binding, per-property, per-row or per-record statuses whenever the method supplies them; the aggregate result may not identify the rejected element.
  5. For DB_SEC_E_PERMISSIONDENIED, reproduce the issue with the smallest command, rowset or definition operation that preserves the same contract boundary.
  6. For DB_SEC_E_PERMISSIONDENIED, apply one evidence-backed correction, then verify that the operation succeeds and does not merely change into a nearby HRESULT.

Corrective actions

  • Action 1 for DB_SEC_E_PERMISSIONDENIED: grant only the minimum permission required for the documented operation.
  • Action 2 for DB_SEC_E_PERMISSIONDENIED: correct impersonation, delegation or service-account selection.
  • Action 3 for DB_SEC_E_PERMISSIONDENIED: surface authorization failure without logging credentials or protected row data.

Practical incident

A Windows service connects using its machine account instead of the configured domain account and can read metadata but not rows; correcting the service identity resolves DB_SEC_E_PERMISSIONDENIED. The diagnostic value comes from retaining DB_SEC_E_PERMISSIONDENIED together with the failing interface and object state, not from reducing every provider result to “database error”.

Implementation guidance

Code handling DB_SEC_E_PERMISSIONDENIED should release OLE DB resources in ownership order, preserve every provider error record, and log granted properties rather than only requested properties. When handling DB_SEC_E_PERMISSIONDENIED, handles such as HACCESSOR, HROW, HCHAPTER and provider-specific region tokens must never be treated as portable integers across object lifetimes.

When DB_SEC_E_PERMISSIONDENIED crosses an abstraction boundary, attach a stable correlation ID and structured fields for the native HRESULT, provider source, interface IID, method, object generation and operation phase. For DB_SEC_E_PERMISSIONDENIED, do not log passwords, access tokens, complete SQL text or unrestricted row values merely to make the event easier to search.

Retry and recovery policy

Retry rule for DB_SEC_E_PERMISSIONDENIED: retry only after authorization or the requested scope changes; repeated attempts under the same denied identity should stop. A safe DB_SEC_E_PERMISSIONDENIED retry must use a changed input, object generation, provider capability or state transition. If the call returning DB_SEC_E_PERMISSIONDENIED could have created, updated, deleted or copied data, determine partial completion before replaying it.

For DB_SEC_E_PERMISSIONDENIED, use bounded retries and preserve cancellation. For DB_SEC_E_PERMISSIONDENIED, configuration and contract failures should normally fail fast; concurrency, resource or transient state failures may justify retry only after their stated precondition changes.

Difference from related HRESULT values

DB_SEC_E_AUTH_FAILED means authentication itself failed, while DB_SEC_E_PERMISSIONDENIED means an authenticated identity lacks authorization. Keep these outcomes separate in telemetry and user-facing remediation because DB_SEC_E_PERMISSIONDENIED requires a different next action.
