The OP is running Samba as a PDC, so 'security = user' is probably okay,
but I would remove it entirely and let Samba decide what it should be ;-)
What is missing is 'unix password sync = yes'
If this was a Unix client, then you would need 'security = domain' and
run winbind, but it is a PDC using tdbsam, so you probably don't. I say
this because I haven't run a PDC for sometime and would urge the OP to
upgrade to AD.
