Much depends on the age of the Isilon system.  Isilon used to run Samba on 
top of their OneFS, but over the past couple of years they moved to the 
Likewise product.

Likewise used to be Open Source, but Isilon was purchased by EMC and then 
EMC/Isilon bought up Likewise.  The GPL version of the Likewise software is 
probably still out there somewhere, but as far as I know all current 
Likewise development has gone proprietary.

...and I don't know what authentication modes they support.
