setAuthCallback
Sets the callback that @domain will use to authenticate incoming requests.
For each request containing authorization, @domain will invoke the callback, and then either accept or reject the request based on @callback's return value.
You can also set the auth callback by setting the property@AuthDomainBasic:auth-callback and property@AuthDomainBasic:auth-data properties, which can also be used to set the callback at construct time.
