Single Sign-On

Single sign-on (SSO) is mechanism whereby a single action of user authentication and authorization can permit a user to access all computers and systems where he has access permission, without the need to enter multiple passwords. Single sign-on reduces human error, a major component of systems failure and is therefore highly desirable but difficult to implement.

Single Sign-On (SSO) is a key feature of the Enterprise Portal that eases user interaction with
the many component systems available to the user in a portal environment. Once the user is
authenticated to the enterprise portal, he or she can use the portal to access external
applications. With SSO in the Enterprise Portal, the user can access different systems and
applications without having to repeatedly enter his or her user information for authentication.
We have 2 types in The Enterprise Portal SSO mechanism
• SSO with SAP logon tickets
• SSO with user ID and password

Systems less than 4.0B does not support Logon Ticket Method, You have to go with User ID & Password method.

To use Logon Ticket Method
Users must have the same user IDs in all SAP systems that are accessed via SSO with SAP
logon tickets. If the SAP user IDs are the same as the portal user IDs, user mapping is not
required. You need to perform the following steps in logon ticket method:
1. Configure Portal Server for SSO with SAP Logon Tickets
2. Configure SAP Systems to Accept and Verify SAP Logon Tickets

If the user ids in the external system and in the portal are different than you have to set up a reference system and map the user ids.
