I've got Netatalk & Avahi running on a local Ubuntu server--I use two different userids, "afp" for Time Machine and "stew" to access my media files etc.

In order to mount a shared directory on my server, I have to click "Connect As..." and enter my userid/password every time, because it always tries to log in using Time Machine's userid. I'm not sure if this is because that userid is set as default, or just because it's the last userid that logged in to that server--either way:

Is there a way to change the default userid for connecting to a given server?

Mega extra credit: I'd love to have this automated, such that my userid, "stew", is always logged in (and heck, it'd be great to have the directories always mounted, too!) whenever the server is available.

Thanks!
