Authentication plug-ins are used in
conjunction with one or more authorization plug-ins to control
access to the content on the server. By adjusting the plug-in
properties, you can specify how a client's
authorization credentials are obtained by the server.
The WMS Digest Authentication plug-in is
available only if Windows Media Services 9 Series is running on the
following editions of the operating system: Windows Server 2003,
Enterprise Edition and Windows Server 2003, Datacenter Edition. If
you are running Windows Server 2003, Standard Edition, this feature
is not supported.
