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.

It is normal… Especially by the fact that iCal Server don't support Basic auth, so the client must do at least one non-auth request to do the Digest workflow. This is just like a browser would do.

It's iCal itself who use this, and it's perfectly good. Resources in iCal Server are accessible by both the username or the UUID. It's not a problem.
