Top Authenticating users through Windows NT Server A user can be authenticated and gain access to the system and its resources, such as a FrontPage-extended web, only if the user has a user account on Windows NT Server. Typically, a system administrator creates a user account for each user and group that has access to the system. To gain access, the user supplies a user name and password when logging on to the system. Windows NT Server compares the user s name and password against the authorized list of user accounts that it maintains. That way, the application can invoke only other applications or system resources, such as files and folders that contain Web content, for which the original user has permissions.
Impersonation also works remotely.
For example, when a user who has permission to author a FrontPage-extended web on a remote computer running Windows NT Server attempts to do so, the FrontPage authoring DLL file, Author.dll, runs as the impersonated user. An ACL is a list that specifies which users and groups have access to its associated file or folder, and what permissions those users and groups have. An ACL is not a file, but rather a property of a file or folder. The security that FrontPage Server Extensions provides is based on ACLs. The IIS Web server is a Windows NT service, which is a special application that starts along with the operating system and runs in the background, without any user interface.
