"NetBIOS domain name\username" format cannot be used with the Kerberos referral mechanism to log on to a computer in a cross-forest environment

Symptoms

This article describes a hotfix for Kerberos authentication that must be installed on Windows Server 2008 R2-based and Windows Server 2008-based global catalogs.

Currently, Kerberos authentication enables a user to log on to a domain-joined computer by using user credentials in one of the following formats:

  • User principal name (UPN)
  • FQDN domain name\username
  • NetBIOS domain name\username

The Kerberos referral mechanism works correctly in all environments when you use the UPN or "FQDN domain name\username" formats. However, when you use the "NetBIOS domain name\username" format, the Kerberos referral mechanism works correctly only in a single forest environment. The "NetBIOS domain name\username" format cannot be used for user accounts in a child domain when the Kerberos referral mechanism is working in a cross-forest environment in which trusts are established among the forests.

For example, when you try to use the "NetBIOS domain name\username" format to log on as a user in a child domain in a trusted forest on a computer that is running Windows 8 Customer Preview, the authentication process fails. However, you can use the "NetBIOS domain name\username" format for user accounts in the forest root domain of the trusted forest.

This issue affects applications that use Kerberos service for user (S4U) extensions to create a context for a user in a trusted forest. For example, consider the following scenario:

  • A user has an application that uses a Kerberos S4U extension on a server in forest A.
  • The user is in the child domain of trusted forest B.
  • The Kerberos S4U extension is invoked to pass the NetBIOS name of the child domain in forest B.

In this situation, the Key Distribution Center (KDC) in forest A cannot generate a Kerberos referral path to trusted forest B, and you receive a "KDC_ERR_S_PRINCIPAL_UNKNOWN (7)" error.

Cause

The global catalog recognizes the NetBIOS names of trusted forest root domains but does not recognize the NetBIOS names of child domains in trusted forests. Therefore, when the KDC in one forest tries to find the KDC of a child domain in another forest by using the "NetBIOS domain name\username" format, the global catalog cannot lookup the domain. This behavior causes the KDC to fail because the KDC cannot create a referral ticket.
