Multiple auth prompts when a website is doing http auth to access intranet for accessing shared resources

[piyush349]

In edge webview2, we observed that when we try to access NetworkShare Connector over intranet, two/more authentication dialogs are prompted (they may appear at the same time in overlapped manner, or with seconds internal)..
This issue is also occur when we try to access the same with the Edge browser. When we try CEF based WebView there is only one Auth prompt.

Thanks for the bug report @piyush349 - it sounds like this is a bug with the underlying authentication flow of Edge. I'll open a bug from this and get it routed to the right folks. Thanks!

@piyush349 Do you see the same behavior in Chrome? Are you doing any authentication handling in CEF that might be supressing this issue?

[piyush349]

@champnic Chrome works fine. We are not doing any additional authentication handling in CEF.
I can see this issue when I am using Edge Browser.

Thanks for confirming!

HI @piyush349, @comanea is looking into this now. In order to better understand what is going on, would you mind sharing your netlog of the connection with us? And if you don't mind listing the steps to repro this network share auth prompt please.

It happen while accessing the Intranet resources. Looking into the Fiddler traces I can see multple request are fired(same) which is giving 401 and because of which we are getting multiple Auth Prompt.
