commit ab442938d5516e8748b4a323f991b6a8aa5bab5a
Author: Jerome Martin <jxm@risingtidesystems.com>

     Added generic auth support in ui_node

     * Replaces Node ACL ad-hoc auth support
     * Allows auth support in TPGT (recently added in iSCSI)


Actually support was added to targetcli in Dec 2011.

Obviously this is another feature that has been in your proprietary 
product for *years*. Can you at least be upfront with us on what the 
features you have implemented but not yet shared publicly are, and what 
your schedule for open-sourcing them is? Or at least highlight the 
differences on the linux-iscsi.org website? Because people look at that 
website and assume those features are in the mainline Linux kernel.
