First of all, thanks for the hard work in releasing a SmartOS image with 
OpenSSH 7 instead of SunSSH.
Since using this build ssh key authentication no longer works though.
I connect from my yosemite macbook using a dsa key and my ssh setup on
the mac side hasn't changed.

I'm guessing the last 2 lines is where it really goes wrong ?
