I just thought I would answer my own email in case anyone else has the same setup. I found out there is obviously some type of bug in the -23 versions of the SASL packages so they just won't work. Once reverting to the -20 or -21 versions, everything works great. My suspicion about the faulty SASL was correct, but since there was only a problem with the daemons themselves and not mupdatetest and imtest, it was difficult to see this. I suppose I should report this to the SASL list, but I'm really not sure what to say since the logging information is rather incomplete.
