You cannot use ADFS to extract binary Active Directory attributes on a computer that is running Windows Server 2003 R2 (919648)


The information in this article applies to:

  • Microsoft Windows Server 2003 R2 Standard Edition (32-bit x86)
  • Microsoft Windows Server 2003 R2 Enterprise Edition (32-Bit x86)
  • Microsoft Windows Server 2003 R2 Datacenter Edition (32-Bit x86)
  • Microsoft Windows Server 2003 R2 Standard x64 Edition
  • Microsoft Windows Server 2003 R2 Enterprise x64 Edition
  • Microsoft Windows Server 2003 R2 Datacenter x64 Edition

SYMPTOMS

On a computer that is running Microsoft Windows Server 2003 R2, you cannot use Active Directory Federation Services (ADFS) to extract binary attributes that are stored in the Active Directory directory service. For example, you cannot access a GUID. Therefore, you cannot pass binary Active Directory attributes to an outgoing Security Assertion Markup Language (SAML) token.

CAUSE

This problem occurs because ADFS incorrectly encodes the data in binary Active Directory attributes by using the ToString() function when the data should be base-64 encoded.
