We have a service provider portal on SAP Netweaver Portal 7.31 serving multiple clients. Generally our users login with user IDs and passwords and authenticate against the UME. We have a hundreds of clients like this. One of the big client wants their employees to seamlessly login to the service provider portal and authenticate using their SAML system. The challenge is how to support other clients with user IDs and password and this client with SAML.
Anybody has any suggestion?
