How to prevent MR Web Viewer from prompting for credentials every time

If you're tired of having to enter your credentials every time MR Web Viewer opens, you've come to the right place.  

In order to display a report in the web viewer, the Management Reporter services must first know what your Active Directory domain account is in order to confirm you are an MR user. The web browser you are using to access the MR report is in charge of getting the credentials. The credentials can be supplied either by prompting the user to enter them or in some cases, can be automatically passed through by the browser. 

IE, Edge (Chromium), and Chrome all use the Control Panel -> Internet Options settings from the operating system. If you want one of those browsers to pass the domain credentials automatically, we recommend setting the MR services path as a trusted site: 

1. Add the address for the Management Reporter services as a trusted site: 

-Go to Control Panel -> Internet Options -> Security -> Trusted Sites. 

-Click the Sites button.  

-Un-check the “Require server verification (https:) for all sites in this zone” checkbox. 

-Add the fully qualified domain name (FQDN) address for the MR services without the port. You can confirm the address by opening a report in the web viewer. For example: http://MRServer.consoso.com 

-Click Close. 

2.  Set the authentication option: 

-Go to Control Panel -> Internet Options -> Security -> Trusted Sites. 

-Click Custom Level.  

-At the bottom, change "User Authentication" to "Automatic logon with current user name and password".  

-Click OK through the windows. 

3.  Close all browser windows and then restart to test.

Firefox is a bit different in that trusted sites must be added manually: 

 -Start Firefox. 

-Go to: about:config 

-Agree to the warning. 

-Search for: network.automatic-ntlm-auth.trusted-uris 

-Add the same FQDN path as above. For example: http://MRServer.consoso.com 

-Step 2 from above must be set for this to work. 

-Restart Firefox to test. 

If the above doesn't work, check if there are any group policy options that may be overriding the local selections. Also, any credentials saved in the browser for the MR path should be cleared. 

If you choose to have the browser prompt for credentials, a tip to enter them less often is to enter them on the first report and then leave that report open in the browser throughout the day. Any subsequent reports that are opened should not prompt for credentials as long as the original report remains open on the other tab. If it prompts for credentials again, you would need to enter them.  

An alternative to using the web viewer is to use the MR Report Viewer application to view reports. The Report Viewer application never prompts for credentials. The choice of what viewer to use is a per-user setting in Report Designer under Tools -> Options -> "Use Management Reporter Report Viewer as default viewer".
