The FilterFlags property contains flags that indicate which events the corresponding ISAPI filter has registered to be notified for. For more information, see ISAPI Filter Design Issues in the Platform SDK.
Because this property is internally configured by IIS, you should consider it to be read-only. Do not configure this property.

NotifyAuthComplete
[IIS 6.0]
Notify if the client's identity has been negotiated with the client. Because of the timing of this notification, the AUTH_USER server variable can be used to reliably obtain the identity of the user. If the value of this property is 1, then the filter registers for the SF_NOTIFY_AUTH_COMPLETE notification. If the value is 0, the filter does not.
