Windows Authentication Packages

Windows authentication packages provide authentication services by implementing package-specific functionality for the LsaLogonUser and LsaCallAuthenticationPackage functions provided by the LSA.

MSV1_0 is an example of a Windows authentication package. The MSV1_0 package accepts a user name and a hashed password, which it looks up in the Security Accounts Manager (SAM) database. Depending on the results of the lookup, the MSV1_0 authentication package accepts or rejects the authentication attempt.

For a list of the support functions the LSA provides for use by Windows authentication packages that require system services, see LSA Functions Called by Authentication Packages.

Windows authentication packages must implement a set of functions that are called by the LSA. For the complete list of functions, see Functions Implemented by Authentication Packages.
