If your Solaris system already has unix system accounts with the same 
usernames as the Windows accounts, then you do not need to run winbind. 
That's how we run our Solaris and Linux systems here.  Unix users are 
populated from ldap using the nss_ldap module, and Samba is a member of 
the domain (security=domain).
