Access tokens are not updated correctly when you enable authentication mechanism assurance in a Windows Server 2008 R2-based domain

Symptoms

Consider the following scenario:
  • You have some client computers that use certificate-based smart card authentication in a Windows Server 2008 R2-based domain environment.
  • You enable the Authentication Mechanism Assurance feature to specify a certificate issuance policy.
  • The smart card authentication logon process includes multiple certificate chains.
  • A user logs on to a computer in the domain by using a smart card.
In this scenario, the Key Distribution Center (KDC) does not set the specific certificate issuance policy, and the user's access token does not contain the expected group membership. Additionally, the KDC validates the certificate with any issuance policy that is available and checks whether the returned certificate chain has the required issuance policy.

Cause

This issue occurs because the certificate chain that the KDC selects does not map the client certificate issuance policies to the issuance policies that are mapped in Active Directory. Therefore, the user's access token does not have the expected group membership. This behavior results in an access control failure.

Note A single user’s certificate can have lots of possible certificate chains in a complex public key infrastructure (PKI) situation. In the design of the authentication mechanism assurance feature, the KDC depends on the certificate APIs to select the best chain to request the mapped groups for the user.
