'Module Name:
' mschapp - MS-CHAP Password Change API
'Abstract:
' These APIs correspond to the MS-CHAP RFC -2433 sections 9 and 10. In order
' to develop an MS-CHAP RAS server that works with an NT domain, these APIs
' are required.
' Only wide (Unicode) versions of these apis will be available. These are the
' 2 callable APIs:
' * MSChapSrvChangePassword
' * MsChapSrvChangePassword2
