Comment 3 for bug 1214636

I've launched an instance from the azure cmdline tools:
$ azure vm create --vm-size=extrasmall --vm-name=sm-saucy1 "--location=East US" --<email address hidden> --no-ssh-password --ssh=22 sm-saucy1 b39f27a8b8c64d52b05eac6a62ebad85__Ubuntu_DAILY_BUILD-saucy-13_10-amd64-server-20130821-en-us-30GB smoser

and I'm able to ssh in fine with the appropriate key.
cloud-init populated /home/smoser/.ssh/authorized_keys correctly

$ cat /etc/cloud/build.info
build_name: server
serial: 20130821
$ cat .ssh/authorized_keys
