Yes, what you describe is a bug I am currently working on, and it will be fixed within a few days.
Sorry about that, but because we use the DOMAIN authentication feature, I have no use for the smbpasswd.dat file, so sometimes I forget about testing that area. Be a little patient, and it will be OK. JYC PLEASE READ THIS IMPORTANT ETIQUETTE MESSAGE BEFORE POSTING: http://www.catb.org/~esr/faqs/smart-questions.html
