Session-based single sign-on is supported for the dialog users of the PI tools. A dialog user has to log on only once for all PI tools, provided that the same browser session is used for each tool access, and that the tools are started from the same SAP NetWeaver Application Server Java.
Single sign-on is also supported by the Runtime Workbench where access to other PI components is required (for example, for component monitoring).
For more information, see Single Sign-On Configuration. See also SAP Note 757373.
