Authentication and Single Sign-On 

The IT scenario Authentication and Single Sign-On describes an example for integrating different systems into a single sign-on (SSO) environment. Single sign-on not only reduces complexity for end users, saving them valuable time, but also reduces administration effort for resetting passwords, thereby contributing to TCO reduction.

When implementing this scenario, users are initially authenticated in the SAP NetWeaver Portal using information that is stored in an external LDAP (Lightweight Directory Access Protocol) directory. After being authenticated, they are issued a logon ticket from the portal that they can use to access the various systems (SAP or non-SAP) in the backend.

Most of the tasks involved with this scenario are configuration tasks. In addition, any administrative tasks that are required are not scenario-specific and are therefore covered in the Administration for User Authentication and Single Sign-On (SSO) in the section that applies to your initial authentication mechanism and in the section about logon tickets.
