What are you using in nsswitch to resolve the user's name?

I suspect you are using something expecting pure rfc2307 attributes,
rather than the built in and rather limited winbind.  The issue is that
in AD, the attribute you want is called unixHomeDirectory.  However,
while limited, you are still best to use the built in winbind and
nss_winbind on the AD DC, which will expect home directories in the
pattern of /home/domain/user, unless you change 'template homedir = ' to
be 'template homedir = /home/%USERNAME%'. 

(To others: This post is not an invitation to re-open past threads on
the topic).
