ERROR_NO_SUCH_PACKAGE
An authentication call named a package that LSA does not know
LSA hosts authentication packages that implement logon and package-specific authentication operations. Applications normally obtain a package identifier and then pass package-specific request data through the LSA connection. This error means the selected authentication package is unknown; it is distinct from a package recognizing the request but rejecting credentials.
Capture the exact package name and the result of LsaLookupAuthenticationPackage before sending any package request. Verify the target system actually provides the package and that the process is not using an ID cached from another boot or another machine. Package IDs are part of the local LSA interaction, not portable protocol constants. For third-party authentication packages, inspect installation and LSA initialization logs/configuration before changing user passwords or account rights.
What to inspect
- Log the authentication package name and lookup result.
- Do not reuse a package identifier obtained on another system or boot context.
- For third-party packages, verify package registration and LSA initialization.
