I've submitted a bug report with NetApp as well.

Jeremy, a more samba-ish related question though:

Why does rpcclient need to call fetch_machine_sid() and subsequently
try to open up the LSA for every type of RPC? i.e. The 'netshareenum'
calls works fine if I just comment this line out.

Thanks for at least reading my post!
