SAPGUI for Single Sign-on
SAPGUI on Microsoft Windows or Internet Explorer can also be used for single sign-on. There are several portal-based authentication applications for single sign-on. Single sign-on also works in the Java GUI.
Criticism of using SAPGUI for authentication to SAP Server access
SAP is a distributed application, where client software (SAPGUI) installed on a user's workstation is used to access the central SAP server remotely over the company's network. Users need to authenticate themselves when accessing SAP. By default, however, SAP uses unencrypted communication which allows potential company-internal attackers to get access to usernames and passwords by listening on the network. This can expose the complete SAP system, if a person is able to get access to this information for a user with extended authorization in the SAP system. Information about this vulnerability is publicly accessible on the Internet.
