SEC_E_INSUFFICIENT_MEMORY
SEC_E_INSUFFICIENT_MEMORY signals this condition: SSPI could not allocate enough memory to complete the requested security operation. This status does not identify an authentication policy problem by itself. It means the security package could not obtain the memory it needed while building or processing an authentication context.
What to check
- Capture the process name, security package, target, and authentication step that produced the status.
- Check whether the failure is isolated to one process or accompanies system-wide memory pressure, handle exhaustion, or repeated authentication retries.
- Investigate the earliest resource-related events before retrying the sign-in or connection.
