Configuring Authentication and Single Sign-On 

User authentication and Single Sign-On is an element of your security policies that you can use to protect access to your system infrastructure by securely establishing and propagating the identity of a sender of an access request.

●      User authentication includes the process of securely establishing the identity of a user as a client requesting access to a server system.

·        Single Sign-On complements user authentication and includes the process of authenticating an access request once and transparently propagating the identity of an already authenticated user for access to multiple backend systems.

You can use authentication and SSO to enable secure points of access to your systems in open environments, such as the Internet.

SAP NetWeaver offers several mechanisms for authenticating users and establishing a Single Sign-On environment. The mechanisms you use depend on your system landscape. Not all mechanisms are available for all SAP NetWeaver components. For an overview of the mechanisms available with AS Java and how they work, see:

·        Authentication for Web Based Access

·        Authentication for Web Services

·        Authentication for Communication between Systems

To configure these mechanisms, see:

●      Single Sign-On for Web-Based Access 

●      Single Sign-On for Web Services 

●      Single Sign-On for Interaction Between Systems  

●      Single Sign-On for Java Remote Method Invocation 

●      Single Sign-On for Resource Adapters and JCA

There are also a few additional features available with the portal. For more information, see Portal Authentication Infrastructure.
