HKLM\Software\Policies\Google\Chrome
Setting the policy assigns servers that Google Chrome may delegate to. Separate multiple server names with commas. Wildcards, *, are allowed. Leaving the policy unset means Google Chrome won't delegate user credentials, even if a server is detected as intranet. Example value: *.example.com,foobar.example.com
