Prompting of credentials on Edge browser despite already logged in on client PCs

GQ 26

We were accessing our RSA Archer application on IE 11 via SSO, and all has been well. But we are required to move on to Edge browser, and that's where we started having the Windows Security credential prompt coming out, whenever we tried to access the application on Edge browser.

The strange thing is, the application is able to load up on Edge properly, in the logged in state, and then the prompt will appear. We can just click on Cancel to close the prompt and we are able to use the application normally. All end users on their client PCs encountered the same problem.

We want to remove the credentials prompt. The RSA support team has confirmed it is not an issue of their product, since there's no problem over at IE. What we have done on our end on the servers:

Enabled SSL on our load balanced environment
Updated the web.config file of the application with the entry below:
<security mode="Transport">
<transport clientCredentialType="Windows" />
</security>
Configure IIS settings to allow Anonymous Authentication instead of Windows Authentication for the application pages.

Will greatly appreciate some assistance or suggestions on how to move forward. Thanks!

Hi @GQ ,

Which version of Edge are you using? Have you tried to use chrome, firefox or any other browser to access site and if they have same issue?

Try to clear cache and stored password on Edge. Or you can create a new Inprivate window to access it. Check if the issue still exists.

If all these have no help, could you please provide some sample code so that I can reproduce the issue. I also need you show the complete web.config and applicationhost.config file. Especially the authentication section <location path="default"> <system.webServer>...</system.webServer> of the site.

After finally being able to investigate via the development tool for this, we discovered that apparently, the behavior of some components / javascripts were different on IE / Edge.

On IE, if the components / javascripts took too long to load, it will fail (status 304) and retry again until it succeeded (status 200).

On Edge, instead of failing, it will go into "Pending", and then the credentials prompts pops out, and usually there's more than one prompt. We suspect the number is based on the number of pending components / javascripts that are in "Pending". Clicking on Cancel on the prompt will caused the components to not load (status 304), and no retry will happen like in the case of IE.

Able to advise what's wrong? Is there a timeout in the Edge settings?

Hi @GQ ,

Edge doesn't have any setting about timeout. If some components take long time to load, consider that using compression to speed up the speed at which the server responds to resources to the client.

And please try to use this policy, enable it and add your server name in.

I am getting this as well from learn.microsoft.com.
Running PowerShell ISE as admin.
PowerShell Command: get-help get-services -online
Even though Chrome is default, Edge will open.
If I try to click in menu or anything, will prompt for Windows Credentials.
I can cancel.

Environment:
Windows 10 Build 19045

PowerShell 5.1

Microsoft Edge Version 115.0.1901.183 (Official build) (64-bit).

Also, if I wait a bit and come back to cancel the credentials, it will error out.
