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

The most widely-used supported mechanisms are listed below. For a complete list, see the link provided 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.

        SAP logon tickets

The Quality Inspection Engine (QIE) supports the use of logon tickets for SSO when using a Web browser as the frontend 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.

        Client certificates

As an alternative to user authentication using a user ID and passwords, users using a Web browser as a frontend 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.

        Security Assertion Markup Language (SAML) 2.0

SAML 2.0 provides a standards-based mechanism for SSO. The primary reason to use SAML 2.0 is to enable SSO across domains.
