Specifies which servers to enable for integrated authentication. Integrated authentication is only enabled when Microsoft Edge receives an authentication challenge from a proxy or from a server in this list.
Separate multiple server names with commas. Wildcards (*) are allowed.
If you don't configure this policy, Microsoft Edge tries to detect if a server is on the intranet - only then will it respond to IWA requests. If the server is on the internet, IWA requests from it are ignored by Microsoft Edge.
Example value: *contoso.com,contoso.com
