AuthPersistence Metabase Property

Applies To: Windows Server 2003, Windows Server 2003 with SP1

The AuthPersistence property specifies authentication persistence across requests on a connection using NTLM authentication. The default for NTLM is false (0), for legacy reasons, while all other authentication schemes assume the single request to be true (1). When the AuthPersistSingleRequest flag is set to true on this property, IIS 6.0 automatically reauthenticates every request, even those on the same connection. This behavior is different on IIS 5.0 and IIS 5.1, where there were two other flags for the AuthPersistence property specifying persistence based on the existence of a proxy server.
