How could I enable this on IIS6.0/windows 2003 AND IIS5.1/WinXP Pro SP1?

Apparently, doing so would enable security token to be passed on to SQL
Server or Active Directory? Using Integrated Windows authentication does not
work, at present.

Hi,

When enabling the Kerberos, the user credential(password etc) will not be
passed in the domain networking. AD passes the hash value of the user
credential instead. This resource will explain the Kerberos in Windows 2003
very well to us:
Kerberos Authentication in Windows Server 2003
http://www.microsoft.com/technet/pr...3/technologies/
featured/kerberos/default.mspx

So for your scenario, the two kb articles introduces how to enable the
kerberos in IIS5.1:
326089 How to enable IIS to use Kerberos authentication on a computer that
is
http://support.microsoft.com/?id=326089

215383 How to configure IIS to support both Kerberos and NTLM authentication
http://support.microsoft.com/?id=215383

For enabling kerberos in IIS6.0, this article from operation guide
introduces the steps:
Configuring Constrained Delegation for Kerberos (IIS 6.0)
http://www.microsoft.com/technet/pr...3/Library/IIS/d
f979570-81f6-4586-83c6-676bb005b13e.mspx

Furthermore, after enabling kerberos, we will also need to configure the
SQL server to support it.
Information about SQL Server 2000 Kerberos support, including SQL Server
virtual servers on server clusters
http://support.microsoft.com/?id=319723

At last, for any configuration issue at IIS, this kb article will be some
helpful:
326985 HOW TO: Troubleshoot Kerberos-Related Issues in IIS
http://support.microsoft.com/?id=326985

Please feel free to let me know if you have any further question on this
matter.
