[Bug 1201969] [NEW] cloud-init parses Azure setting "DisableSshPassword" incorrectly

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

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
