STATUS_INSUFFICIENT_LOGON_INFO
The logon package cannot build a complete validation request
A logon path may require a user name, domain or account authority, workstation, logon type, and package-specific credential data. This status indicates that the available information is incomplete, not necessarily that the supplied password is wrong.
Capture the logon provider and package before troubleshooting. Cached, local SAM, domain, certificate, and web-account sign-in paths require different identity fields. Adding a guessed domain can direct the request to the wrong authority.
What to inspect
- Record the logon type, authentication package, user name form, domain, and workstation fields.
- Determine whether the request targets local SAM, Active Directory, or an online account provider.
- Compare the request structure with a successful logon of the same type while excluding secret values.
