UseDigestSSP Metabase Property (IIS 6.0)
Advanced Digest authentication uses the UseDigestSSP metabase property to switch between Digest and Advanced Digest security support provider interface (SSPI) code. If this property is set to false, Digest authentication is used. In all other cases (true, empty, or not set), IIS uses Advanced Digest authentication. If you configure UseDigestSSP at the W3SVC level of the metabase, all child keys inherit their configuration from that level.
If Digest SSPI code is used and dedicated application mode is selected, the Local System account must be used as the identity.
The World Wide Web Publishing Service (WWW service) must be restarted before changes to this property take effect.
You can configure this property at the following locations in the IIS metabase.
