Had a real tough time getting this installed .. Please don't ask why, but I am forced to use OS X at all, let alone the client version... bit of a nightmarish situation. Installing from darwinports was the easiest method.. everything appeared to be working fine, the .db was updating when I added new users, but I couldn't authenticate from cyradm and I was seeing "saslpasswd2: Couldn't update db" in the logs. Anyway, after banging my head against my desk for a while I figured out that for whatever reason, it seems you MUST set a proper hostname. do NOT leave it at the os x default. Here's hoping this shows up in archives and saves some other poor soul some time. jeff d. "Quidquid latine dictum sit, altum sonatur."
