Your smb.conf is mostly correct and if there is a user in AD (and only
in AD) called 'zhangyy' you should be able to log in, provided that
libnss_winbind and PAM are set up correctly. If you cannot log in, then
I would stop smbd, nmbd and winbindd, go to /var/lib/samba and remove
all the .tdb & .ldb files under that directory, restart Samba and run
'getent passwd zhangyy', if this produces output, then you are good to
go. I would also remove any users or groups called 'zhangyy'
from /etc/passwd or /etc/group if they exist.

It might also be a good idea to read this:
