Default domain

Type the name of a domain against which you want users to be authenticated by default. Any users who do not provide a domain name when they log on to your site are authenticated against this domain.

Realm

Type the DNS domain name or address that will use the credentials that have been authenticated against the default domain. Providing a Realm is optional for Basic authentication.

	Important
	If you enter the default domain name in the Realm box, your internal Microsoft Windows domain name may be exposed to external users during the user name and password challenge.
