I have Samba set up as a PDC and I have the global parameter 'unix password sync' set to yes (which should change the password in both smbpasswd and /etc/passwd). I can't seem to find any documentation on how the windows user can change their password. I've tried ctl-alt-del which brings up the the windows security screen and clicked on change password but it does not take. It complains that my user name or old password is wrong or I might have my caps key on.
