This is ok, the _sndio user is to avoid running the server with root privileges, it's not involved in the "authentication" process. You can find slightly more details about how it works in the AUTHENTICATION section of the sndio(7) man page. The simpler -- and most natural imho -- would be configure mpd to use unix domain sockets (instead of TCP) and to run it as your user id instead of _mpd. If you can't, you can cheat by copying mpd's ~/.aucat_cookie in your home directory (it must have mode 0600) this way aucat will consider _mpd and you are the same person. After all, I guess you run _mpd for you ;) -- Alexandre
