NetApp Cluster Mode – Active Directory Authentication setup

Cluster mode is an awesome beast. I say beast, because everything takes MANY more steps to do. Say you want to just enable SSH or OnCommand System Manager client access to your base level cluster? Not so fast… there’s lots of steps before that.

  1. License CIFS
  2. Make a CIFS vserver
  3. Add an Authentication “DOMAIN-TUNNEL”
  4. Add User entries for every domain user + application + role
  5. Profit!

Here I will walk you through what it takes to create do all the crap I listed above.
