Regd SAML 1.1 Configuration in SAP Portal 7.01

Dear All

We are planning to configure SAML1.1 in our SAP Portal 7.01 SP11 system. I have gone through several blogs & guides to collect the data required for configuring the same.

Our scenario is we are planning to access ERP data using web service from mobile apps. In order to access the web service we would like to use SAML for authentication and SSO. Here my identity provider (SAML Source Site) is SAP Portal 7.01 & service provider (SAML Destination site) is my SAP ABAP backend system which has SSO established with SAP Portal using SAP Logon tickets

On successful authentication i have to fetch ERP data using the webservice.

How do I accomplish this case ? In most of the blogs and guides SAML is configured between a separate identity provider and a service provider.

Request your thoughts at the earliest. Kindly revert for any clarifications

Many Thanks !!
