Windows: Kerberos broken in current devel?

All of a sudden I’m getting some nasty winrm errors in my lab env. I’m building my ansible control node from the same script every time, and the windows boxes haven’t changes. This is what I’m seeing:

<thansiblewinDC.ansib.le> ESTABLISH WINRM CONNECTION FOR USER: ansible@ANSIB.LE on PORT 5986 TO thansiblewinDC.ansib.le
<thansiblewinDC.ansib.le> WINRM CONNECT: transport=plaintext endpoint=https://thansiblewinDC.ansib.le:5986/wsman

<thansiblewinDC.ansib.le> WINRM CONNECTION ERROR: 401 Unauthorized.
Traceback (most recent call last):
File “/home/ansible/ansible/ansible/lib/ansible/plugins/connection/winrm.py”, line 126, in _winrm_connect
protocol.send_message(‘’)
File “/usr/local/lib/python2.7/dist-packages/winrm/protocol.py”, line 190, in send_message

File “/usr/local/lib/python2.7/dist-packages/winrm/transport.py”, line 99, in send_message
raise UnauthorizedError(transport=‘plaintext’, message=ex.msg)
UnauthorizedError: 401 Unauthorized.

Looks like Ansible is attempting a plaintext login even tho I’m using a domain user (“@”). I also tried setting the new “ansible_winrm_transport”: “kerberos” variable, but the problem persists.

my bad somehow. Redeployed the ctrl node and everything worked.
