TIdOnAuthorization is the event type signalled to the TIdHTTP.OnAuthorization property. 

VUserName and VPassword are the authentication identity and credentials found in the HTTP request, and can be updated by the TIdOnAuthorization event handler.

TIdOnAuthorization is used after a TIdOnSelectAuthorization event has been signalled to select and create the authentication method for the HTTP client.
