How to disable the authentication on the Diagrams tab in Power Monitoring Expert 8.x?
Issue:
In Power Monitoring Expert 8.x, a user is prompted with an authentication dialog when accessing the Diagrams tab (or the <servername>\ION webpage) The user is required to enter the Windows credentials in order to access.

Product Line:
Power Monitoring Expert 8.x

Environment:
Power Monitoring Expert Web Applications

Cause:
Power Monitoring Expert 8.x introduced password protection for the ION virtual root (the Diagrams tab in Web Applications). It requires that user enter their Windows credentials in order to authenticate with the webpage.

Resolution:
*Warning: Take backups of any files prior to modifying them. Ensure the backups are in a location that will not be overwritten (i.e. the Desktop).

The authentication requirement can be disabled by editing the \Power Monitoring Expert\system\webreach\web.config.

1) In the web. config file locate the following line of code: <deny users="?" />
2) Change this to: <allow users='*' />

Once this is done, you can access the ION virtual root without providing credentials.

Additional Note:
If a browser is run on the PME server, the ION virtual root will always be available without requiring authentication. The authentication dialog will only appear if the browser is run on a remote machine.

For information on disabling authentication for later versions of the software, see FA364347 .
