Oracle AS SSO : How to get the User DN in a Java Application?

The Oracle AS 10.1.2 Single Sign on places useful user information in the HTTP request Headers. The partner application can access these request headers & get this useful information.

The authenticated user's distinguished name ( DN ) is a very important attribute. The DN can be used to pull out more information about the user from Oracle Internet Directory - e.g : the email address, the phone number, etc.

You can easily get the user dn of the authenticated user from the request , by using this code snippet :-

String strUserDN = request.getHeader(“Osso-User-Dn”);

The DN can then be coupled with a simple JNDI Code to retrieve other attributes.
