Hello, I'm having troubles getting the remote_user cgi variable when using basic authentication.  The basic auth itself seems to work fine.  The browser challenges me, I enter a user/pass, and the page loads.  However request.getRemoteUser() is returning null.

Here is the bits that are setting up the basic auth handler:

I've Googled quite a bit and I can't find any guides that indicate that anything special needs set up for remote user to be available.  I also found the exchange attribute class for remote user in Undertow, but can't find any docs or guides at all that indicate how it is to be used or if I need to be doing anything with it in regards to basic auth.

Can someone provide a sanity check on what is missing for the remote user to be available?
