Unencrypted communications allowed in WinRM configuration

[sinap-se]

This file in question appears to be misconfigured to allow unencrypted connections to and from servers and clients making use of WinRM: ansible_winrm.ps1. Within a given network it may not be of particular concern but when using CredSSP with a remote authentication server the credentials end up being donated to any hops along the way in the clear.

The lines in question:

cmd.exe /c winrm set "winrm/config/service" '@{AllowUnencrypted="true"}'
cmd.exe /c winrm set "winrm/config/client" '@{AllowUnencrypted="true"}'

Removing these and rebuilding the Windows images appears to function correctly. It appears that perhaps it was intended for WinRM to be disabled post-ansible run due to the presence of disable WinRM scripts in the scripts mounted for OVA images.
