samba - Jan 2005 - Domain users are not able to login through ftp.

Hi,
 
I have successfully setup a Solaris 8 server that allows Windows AD Users to
login to it (through winbind).  The problem is
that ALL such users can now do so.  Is there a way to control which users are
allowed to login while others are denied access?

I have tried adding 
 
valid users = user
 
and  deny to specific users via

invalid users = user
 
It's not working.  
 
 
One more problem is Domain users are able to login through telnet but domain
users are not able to login through ftp. Please help me to resolve these
problems
 
Please find my smb.conf and pam.conf
