SAML authentication using salesforce.com

Question

In our web application, I want Identity provider (IdP) which authenticate users using salesforce.com.

I have done with Single Sign-On Settings at salesforce.com.

After this setting salesforce provides a metadata file.

Please tell me:

• Is there any other setting I need to make at salesforce.com?
• What to do next in my java code to authenticate the user?

Answer 1

From the Salesforce.com configuration site it is quite simple. 

Here is a sample of what is required on that side to configure with the OpenSSO solution: http://blogs.oracle.com/rangal/entry/saml2_salesforce_com
