SAML2 Profiles for PIV Subjects and Backend Attribute Exchange

FIPS 201 defines a US Government-wide interoperable identification credential for controlling physical access to federal facilities and logical access to federal information systems. The FIPS 201 credential, known as the Personal Identity Verification (PIV) Card, supports PIV Cardholder authentication using information securely stored on the PIV Card. Some PIV Cardholder information is available on-card through PIV Card external physical topology (i.e., card surface) and PIV Card internal data storage (e.g. Magnetic stripe, integrated circuit chip).

SQL Linked Server Query failed with “Login failed for user …”
SQL Server 2005: “Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'”.

SQL Server 2000: "Login failed for user "(null)". Reason: Not associated with a trusted SQL Server connection".

The errors listed above is very typical when deploy linked server with delegation. They actually are thrown by the linked server and pass by middle server to the client application. In this post, I will discuss how to properly configure SQL instances and Windows environment in most common scenario and try to make configuration steps as explicit as possible.
