That is what I assumed initially as well. But after looking into things
just to say I did, it occurred to me that since sasl can store passwords
as md5, I might be able to cut-and-paste my md5 shadow hashes into
sasldb2 somehow. Might you be able to explain why this won't work (not
that I've been able to get it to work of course ;)?
