Title:
  cloud-init parses Azure setting "DisableSshPassword" incorrectly

Status in Init scripts for use on cloud images:
  Fix Committed
Status in “cloud-init” package in Ubuntu:
  Fix Released

Bug description:
  Cloud-init is parsing ovf-env.xml incorrecltly.  Currently cloud-init
  takes the value of DisableSshPasswordAuthentication and uses it to set
  ssh_pwauth. However, DisableSshPasswordAuthentication describes the
  state of whether or not SSH password authentication should be
  disabled, while ssh_psauth is asking if it should be enabled or not.

  To illustration: Setting DisableSshPasswordAuthentication to true
  means that password authentication should be disabled. While setting
  cloud-init ssh_pwauth to true means that password authentication
  should be enabled.

  The fix for this is to set "ssh_pwauth" to the inverse of
  DisableSshPasswordAuthentication
