Claims-based Identity in .NET 4.5 and Windows 8

There was not a ton of new information about WIF and related technologies at Build, but Samuel Devasahayam did a great talk about claims-based access control that contained some very interesting bits of information with regards to future directions.

From his slides:

  • NT Token has a new claims section
  • Enhanced SDDL API’s to work with claims
  • Enhanced user mode CheckAccess API’s to work with claims
  • New ACL-UX
  • Target audits with claims-based expressions

WIF & .NET 4.5

  • WIF is in the box with .NET Framework 4.5
  • Every principal in .NET 4.5 is a ClaimsPrincipal

  • ADFS 2.1 is available now as a in-box server role in Windows 8
