[Samba] How can I tell which users are currently connected?

[Kevin Bramblett]

I am running RHL 7.2 with Samba 2.2.3a using a W2K DC for authentication via
winbind.  From the linux box, how can I find out which users are currently
connected to my box via Samba?  This would help a lot when I need to reboot
the server or restart the samba service because of changes that need to
immediately go into effect.

Thanks
