In response to a 401 the user-agent will repeat the request with credentials included and you should then get a 20X response and an access.log entry with the authenticated username.

As of r10129 (in trunk, and going forward) we disallow use of Basic (even if it's enabled) unless the client is connecting over SSL. If you really want Basic over non-SSL, you have to set Authentication --> Basic --> AllowedOverWireUnencrypted == True.

It's probably true that only Digest and Kerberos are supported in OS X Server / iCal Server :) There is always a gap between "works" and "supported". Mind that gap :)
