I'm using it for what the winbindd man page says:

"winbindd is a daemon that provides a number of services to the Name 
Service Switch capability found in most modern C libraries, to arbitrary 
applications via PAM and ntlm_auth and to Samba itself.

Even if winbind is not used for nsswitch, it still provides a service to 
smbd, ntlm_auth and the pam_winbind.so PAM module, by managing 
connections to domain controllers."

Uh? It's perfectly useful by itself to provide the services mentioned in 
its manpage.

That's not because smbd is not running.
