Configure trusted websites for Microsoft Edge on Linux

Question

Hi,

I'm using Microsoft Edge on Linux in a corporate environment. My laptop is enrolled in the corporate active directory. Thus, once logged, I have a Kerberos token locally on my machine and I would like to benefit of the SPNEGO protocol to simplify the authentication workflow on some intranet websites. Given the Microsoft documentation, on Windows, this is done through Internet Options and some trusted websites options. Under Linux, this option is logically not available.

Can you give me some hints on how to enable SPNEGO under Microsoft Edge on intranet websites on Linux?

P.S.: Linux isn't available in the dropdown list of available operating systems on this Website. I have then chosen macOS.

I have eventually found an answer to my question here: https://techcommunity.microsoft.com/t5/discussions/global-profile-configuration-on-linux/m-p/2432228/highlight/true#M47993. Inspired by how it's configurable for Google Chrome, I searched for configuration of policies for Microosoft Edge under Linux and found this helpful answer.

TL:DR;

• Create a file policies.json under the folder /etc/opt/edge/policies/managed,
• Put the following content inside:

    {
      "AuthServerAllowlist" : "*.mydomain.com,*.myotherdomain.local",
      "AuthNegotiateDelegateAllowlist" : "*.mydomain.com,*.myotherdomain.local",
      "DisableAuthNegotiateCnameLookup" : true,
      "EnableAuthNegotiatePort" : true
    }
  

• Open you browser and check that the policies are correctly loaded though edge://policy/,
• You should get SPNEGO working on the whitelisted domains from now on.
