How to integrate iReceivables with third party Single Sign-On application

Hi,

We are already having a third party Single Sing-On application where some external clients are already registered themselves to access other applications.

Now we are implementing Oracle iReceivables. We would like to provide the iReceivables URL in that 3rd party SSO application so that when the external users login they can access their iRceivables account without  registering again.

For new users who are creating their user name in the 3rd party SSO application should automatically do the self-service registration in iReceivables.

Is there a way to achieve this without implementing oracle Single Sing-On. The 3rd party SSO should directly access iReceivables and do a self-service registration.
