Single Sign-On (SSO) is a specialized form of software authentication that enables a user to authenticate once and gain access to the resources of multiple back-end software systems. SSO enables authorized users to reliably and transparently access software resources across technical system boundaries.
Using SSO with your SAP NetWeaver systems complements user authentication and enables you to decrease the system administrative load when users need to access resources in several different systems. In addition, integrating your systems in SSO environments can strengthen the overall security protection of your systems and reduce security risks associated with securely storing authentication credentials and frequently providing them interactively to multiple back-end systems in complex system landscapes.
SAP NetWeaver enables you to configure various mechanisms, which authorized users must use to access a SAP NetWeaver server system with SSO. The mechanisms you can use and their configuration depends on the underlying technology of the SAP NetWeaver system and the communication channel used for accessing the system.
