We have a SharePoint 2010 environment setup to use Kerberos which works wonderfully - users within our network are authenticated automatically and are not presented with a login prompt.
For some areas of our sites, we require an additional authentication step to be presented to the user. This is mostly for document libraries that contain personal, private data that requires a two-stage authentication to access in order to conform with organization policies currently in place.
Is there a method to apply a second level of authentication to a document library, page, or site within a site collection in order to access secure, private data?
Thanks
