I need to develop SSO solution to work with Google App application. So I thought of calling Salesforce Webservice and get Currently logged user. For that i have to send Session Id.

But Requirment Checklist says we shouldn't

Implement controls to protect the Salesforce Session Id. Specifically:

• Session ID should always be encrypted in transmission
• Session ID should not be sent to third parties (Example: Google Analytics)

Is there anyway of doing this without sending Session Id?

Is OpenID supported in Salesforce ?

I have followed SSO exmple mentioned above. But its not working properly.

Do I need to have Enterprise Saleforce account ? or Can do it with Developer account ?
