hi Krishna
thanks for your reply.
here is article on how Java Netweaver supports OpenID
http://scn.sap.com/docs/DOC-17132
but i have found nothing regarding ABAP Netweaver support for OpenID .
( ABAP NW server (SAP NetWeaver Gateway) is a requirement Fiori, and we need to implement OpenID for Fiori mobile applications.)
regards,
Tom
