Sales Cloud and Siebel Integration via Web Services

Hi,

    I m working on integration between Sales Cloud and Siebel where Opportunity created in Sales Cloud is also inserted in Siebel with associated Contact and Account details.

For this while registering the Siebel wsdl file in Sales Cloud I had used authentication as none and the username and password was added in the Siebel wsdl url itself.

Now I had created a Siebel user in Sales Cloud and removed the username and password details from the Siebel wsdl url and now using authentication as Invoke with current user credentials using SAML in Sales Cloud and invoking the Opportunity creation web service in Sales Cloud with same Siebel user, created in Sales Cloud.
