Single Sign On using Websphere 6.1 server and Kerberos on Windows 2003

[Palayoor Thomas]

We are trying to achieve Single Sign On (Log on) using the following components:

1). Websphere server 6.1
2). Kerberos and Key Distribution Center
3). Microsoft Active Directory contains the user credentials
4). Microsoft Active Directory is installed on a Windows 2003 server

We have enabled the websphere 6.1 sso and the other security settings required. Created some test users in the Active Directory. Set the stand alone directory from the WAS 6.1 as MS AD. A sample web application is deployed over WAS 6.1 Whenever we access the appln., it's asking for the userid /pwd everytime. We are not getting Single Sign On Behavior.

Could anyone help on this scenario?
