I am trying to use DisableAuthNegotiateCnameLookup flag not to use canonical DNS name of user when generating a Kerberos SPN. However the flag doesn't work and canonical DNS name is still used instead of the original URI. Here is how I set disable-auth-negotiate-cname-lookup flag.

var settings = new CefSettings();
settings.CefCommandLineArgs.Add("disable-auth-negotiate-cname-lookup", "true");
settings.CefCommandLineArgs.Add("auth-server-whitelist", "*");
settings.CefCommandLineArgs.Add("auth-negotiate-delegate-whitelist", "*");

I have struggled on this issue for weeks and still could not find answer or workaround solution. I have tried different CefSharp version v93/v92/v91 and none of them works. Hopefully someone can help me and give me some suggestion. Thanks in advance.

This should probably be in the generic support section as it's not CefSharp specific.

CEF only supports a subset of command line args, if it doesn't work then code changes are likely required.

As a test you can try disabling CEFs request interception.
