If your new users work, but the original users don't, it would seem that 
there must be a difference between them, what I do not know. It should 
be easy to find out, make sure that ldb-tools is installed and try 
searching for a user that works, then one that doesn't and compare them i.e.

ldbsearch -H /var/lib/samba/private/sam.ldb 

This displays my AD record when run on my Debian wheezy AD DC
