BASIC authentication mechanism is ignored when it is configured to be silent and incoming requests do not contain Authorization header. Currently, we do not log when the mechanism is ignored. 

This issue is to enhance logging of silent BASIC authentication mechanism. 

The code for the BASIC authentication mechanism can be found here. Search for references to "silent".

An example of how to add a trace logging message can be found here:
