I discovered today that Samba appears to be uncooperative when trying to connect from a single machine to two or more of its shares using different user names. This is a probably a pretty esoteric problem, I realize, but came into play when I was troubleshooting another user’s account without disconnecting shares mounted under my own user name first. The client machine was running Windows XP, the server Ubuntu 7.10 (Gutsy Gibbon).
