    Suresh,

    Once the user is authenticated to the portal, he can use the portal to access external applications without having to repeatedly enter his information for authentication.That is the basic idea of SSO.

    It can be done based on logon tickets or user mapping.The first approach is used when the same id exists in the backend and portal and involves importing a certificate while the second is used when both ids are different and involves mapping of the user-id.

    This is the basic idea.You can find a lot on sdn and help.sap.

    Pls consider rewarding points if helpful

    Hi Suresh,

    Single Sign On(SSO) allows a user to login to the portal once and thereafter start applications & network logon sessions without further aunthentication requests.Thus with a single user authentication and authorization can permit a user to access all systems where he has access permission, without the need to enter multiple passwords.

    The various methods available are:

    SSO with Logon Tickets

    SSO with User id and password.

    For more info on this see this linkhttp://help.sap.com/saphelp_nw2004s/helpdata/en/89/6eb8deaf2f11d5993700508b6b8b11/content.htm">link>.

      Hi Suresh,

      For SSO with user mapping, suppose u want to connect to a SAP transaction. Then u should first create a system representing sap system in Portal. Enter the details. Then create a system alias through which your system is referenced. Now go to User Mapping. Select ur system. Now map your user id to SAP system's user id and password. Create a sap transaction iview and enter the details. On previewing u can see ur SAP transaction without having to enter ur login details in SAP system.

      Logon tickets represents the user credentials. The portal server issues a logon ticket to a user after successful initial authentication. The logon ticket itself is stored as a cookie on the client and is sent with each request of that client. It can then be used by external applications such as SAP systems to authenticate the portal user to those external applications without any further user logons being required.

      Refer help.sap for more details.

      Regards,

      Pooja.

    Hi Suresh,

    Single Sign On enables you to login to all systems in the landscape without asking for any authorizations.Three methods are prominent.

    1.Basic User Id & Password

    2.SAP logon Tickets

    3.X.509 digital certificates

    Apart from this you have External Access Management System tools to enable single sign on.Extensive documentation is found in SDN.

    Please use the SAP TREX Search box in SDN.

    This is a good link to start:

    Hi Suresh,

    SSO - By logging in to portal once, you are able to access SAP R/3, BW, CRM, etc. without logging in again to any of these systems ( If SSO is not there, then you have to loggin to each of the systems )

    SSO can be achieved by

    1. Logon Tickets

    2. UIDPW

    Logon tickets - If the user id of portal and user id of SAP R/3, BW, CRM etc are same.

    How this is achieved?

    The certificate of EP is imported into SAP R/3, BW and CRM inturn the certificates of SAP R/3, BW, CRM etc are imported into Portal. Based on this certificate, the login ids are linked.

    UIDPW - The portal user id and SAP R/3, BW, CRM etc ids are different. In this case, in the portal user mapping is done. Here the portal id is linked with the SAP R/3, BW, CRM ids and password is passed between them.

    Regards

    Arun
