caption: Enable Ambient Authentication for profile types.
desc: |-
  Configuring this policy will allow/disallow ambient authentication for Incognito and Guest profiles in <ph name="PRODUCT_NAME">$1<ex>Google Chrome</ex></ph>.

        Ambient Authentication is http authentication with default credentials if explicit credentials are not provided via NTLM/Kerberos/Negotiate challenge/response schemes.

        Setting the <ph name="REGULAR_ONLY_OPTION_NAME">RegularOnly</ph> (value 0), allows ambient authentication for Regular sessions only. Incognito and Guest sessions wouldn't be allowed to ambiently authenticate.

        Setting the <ph name="INCOGNITO_AND_REGULAR_OPTION_NAME">IncognitoAndRegular</ph> (value 1), allows ambient authentication for Incognito and Regular sessions. Guest sessions wouldn't be allowed to ambiently authenticate.

        Setting the <ph name="GUEST_AND_REGULAR_OPTION_NAME">GuestAndRegular</ph> (value 2), allows ambient authentication for Guest and Regular sessions. Incognito sessions wouldn't be allowed to ambiently authenticate.

        Setting the  <ph name="ALL_OPTION_NAME">All</ph> (value 3), allows ambient authentication for all sessions.

        Note that, ambient authentication is always allowed on regular profiles.

        In <ph name="PRODUCT_NAME">$1<ex>Google Chrome</ex></ph> version 81 and later, if the policy is left not set, ambient authentication will be enabled in regular sessions only.
