So, I may be in a position where I need to support mounting Windows CIFS shares (from an EMC Celerra) to my RHEL clients.  At scale of over 100,000 users.  I ran across some notes on doing this with kerberos auth to the AD realm which seems the most likely way to do this.  This method seems…not overly well understood from my google searches.  So assuming RHEL 5.5 or RHEL 6 how do I get this to work?
