Integration into Single Sign-On Environments 

Use

The Accounting Engine supports the Single Sign-On (SSO) mechanisms provided by SAP Web Application Server ABAP. Therefore, the security recommendations and guidelines for user management and authentication that are described in the Security Guide for SAP Web Application Server also apply to the Accounting Engine.

The mechanisms supported are listed below.

Secure Network Communications (SNC)

SNC is available for user authentication and provides for an SSO environment when using the SAP GUI for Windows or Remote Function Calls.

For more information, see Secure Network Communications (SNC) in the SAP Web Application Server Security Guide.

SAP Logon Tickets

The Accounting Engine supports the use of logon tickets for SSO when using a Web browser as the front end client. In this case, users can be issued a logon ticket after they have authenticated themselves with the initial SAP system.  The ticket can then be submitted to other systems (SAP or external systems) as an authentication token. The user does not need to enter a user ID or password for authentication but can access the system directly after the system has checked the logon ticket.

For more information, see SAP Logon Tickets in the SAP Web Application Server Security Guide.

Client Certificates

As an alternative to user authentication using a user ID and passwords, users using a Web browser as a front end client can also provide X.509 client certificates to use for authentication. In this case, user authentication is performed on the Web server using the Secure Sockets Layer Protocol (SSL Protocol) and no passwords have to be transferred. User authorizations are valid in accordance with the authorization concept in the SAP system.

For more information, see Client Certificates in the SAP Web Application Server Security Guide.
