I've got samba3 setup as PDC, with ldap backend as the userbase. This has been working for quite some time, with samba3 3.0.1rc3. I've upgraded to 3.0.4 and suddenly the passwords don't match. A login results in a password mismatch and since NT passwords are in MD5 format, what has changed from 3.0.1rc3 to 3.0.4 to warrant this drastic effect?
