When setting the "User Must Change Password at Next Login" flag via usrmgr the user is not prompted to change their password. The various Password fields in password backend (tdb) as viewed using pdbedit are all set to zero, so it is doing something. Setting this using "net sam pwdmustchangenow" works correctly (i.e. the users is prompted to change their password). It also sets all the password fields to zero, but I guess it must be doing something else as well. System is Centos 5.1 x86_64. Samba is a v3-0-test GIT snapshot from 26 Apr 2008.
