trying to connect to Windows winRM using kerberos winrm - python-2.7

Question

so I have tested this under several different variations. I have a lab with Windows 2008 R2 servers and RHEL6 and Python2.6 installed. I am able to use ansible as means to remote into the windows server and perform a ping (I have followed all the instructions on how to do this).
I get the problem of not being able to do this with Rhel 7 and python2.7, however I am not sure that the difference in python versions is whats stopping me.
I constantly get this hostname_override error...

With ansible it looks like this, the same hostname_override error:

}
Let me know what else I can try, also on the Windows 2008R2 server i can see that the linux box is trying to connect in the security event log. Not sure what else is going on. Again, this works in RHEL6 on 2 different windows 2008R2 servers.

Answer 1

Likely you have a mismatch in versions between winrm and requests-kerberos. I had the same issue when I had winrm installed via pip and requests-kerberos install via apt.
Verify that you are using a single package manager for all installations.
