Active Directory Support
++++++++++++++++++++++++
If you wish to connect to domain accounts published through Active Directory (as opposed to local accounts created on the remote host), you will need to install the "python-kerberos" module on the Ansible control host (and the MIT krb5 libraries it depends on). The Ansible control host also requires a properly configured computer account in Active Directory.
Ansible supports both local accounts and domain accounts on Windows, to use domain accounts you can use either of these authentication method;
- NTLM
- Kerberos
NTLM authentication can be used on versions of pywinrm>=0.2.0 and does not need any special configuration on the Ansible control host. To use NTLM set ``ansible_winrm_transport=ntlm`` in the host_vars.
To use Kerberos you will need to install the "python-kerberos" module on the Ansible control host (and the MIT krb5 libraries it depends on). The Ansible control host also requires a properly configured computer account in Active Directory.

Examples
++++++++
Below are some examples of how to set your inventory based on the auth method chosen. These should all be defined in the group_vars/windows.yml file.
Basic Auth
----------
Inventory setup for Basic auth::
ansible_user: USER
ansible_password: SecretPasswordGoesHere
ansible_port: 5986
ansible_connection: winrm
Certificate Auth
----------------
Inventory setup for Certificate auth::
ansible_port: 5986
ansible_connection: winrm
ansible_transport: certificate
ansible_winrm_cert_pem: path to the client authentication certificate file path in PEM format
ansible_winrm_cert_key_pem: path to the client authentication certificate key file path in PEM format
Kerberos Auth
-------------
Inventory setup for Kerberos auth, note: specifying ansible_password does not make any difference here, you need to have obtained a valid Kerberos ticket outside of Ansible for this to work::
ansible_user: USER@DOMAIN.COM
ansible_port: 5986
ansible_connection: winrm
NTLM Auth
---------
Inventory setup for NTLM auth::
# it is suggested that these be encrypted with ansible-vault:
# ansible-vault edit group_vars/windows.yml
ansible_user: DOMAIN\USER
ansible_password: SecretPasswordGoesHere
ansible_port: 5986
ansible_connection: winrm
ansible_transport: ntlm
ansible_user: Administrator
ansible_password: SecretPasswordGoesHere
ansible_port: 5986
ansible_connection: winrm
# The following is necessary for Python 2.7.9+ when using default WinRM self-signed certificates:
ansible_winrm_server_cert_validation: ignore
Other Options
-------------
There are other inventory options you can set for additional configuration of the WinRM connections::
* ``ansible_winrm_scheme``: Specify the connection scheme (``http`` or ``https``) to use for the WinRM connection. Ansible uses ``https`` by default unless the port is 5985.
* ``ansible_winrm_path``: Specify an alternate path to the WinRM endpoint. Ansible uses ``/wsman`` by default.
* ``ansible_winrm_realm``: Specify the realm to use for Kerberos authentication. If the username contains ``@``, Ansible will use the part of the username after ``@`` by default.
* ``ansible_winrm_transport``: Specify one or more transports as a comma-separated list. When older versions of pywinrm <0.2.0, Ansible will use ``kerberos,plaintext`` if the ``kerberos`` module is installed and a realm is defined, otherwise ``plaintext``.
* ``ansible_winrm_server_cert_validation``: Specify the server certificate validation mode (``ignore`` or ``validate``). Ansible defaults to ``validate`` on Python 2.7.9 and higher, which will result in certificate validation errors against the Windows self-signed certificates. Unless verifiable certificates have been configured on the WinRM listeners, this should be set to ``ignore``
* ``ansible_winrm_*``: Any additional keyword arguments supported by ``winrm.Protocol`` may be provided.
Attention for the older style variables (``ansible_ssh_*``): ansible_ssh_password doesn't exist, should be ansible_ssh_pass.

You'll run this command again later though, to make sure everything is working.
Since 2.0, the following custom inventory variables are also supported for additional configuration of WinRM connections::

Verifying Windows Configuration
```````````````````````````````
After you have set up the Windows host you can use the following commands to verify the setup to ensure Ansible can communicate with the host.
Verify WinRM Listeners
++++++++++++++++++++++
To see what listeners are currently active you can run the following ``winrm`` command in PowerShell::
#!powershell
PS C:\> winrm enumerate winrm/config/listener
Listener
Address = *
Transport = HTTP
Port = 5985
Hostname
Enabled = true
URLPrefix = wsman
CertificateThumbprint
ListeningOn = 127.0.0.1, ::1
Listener
Address = *
Transport = HTTPS
Port = 5986
Hostname = WINDOWS-SERVER
Enabled = true
URLPrefix = wsman
CertificateThumbprint = 1234567890ABCDEF111213141516171819101A1B
ListeningOn = 127.0.0.1, ::1
In the above example we can see both a HTTP and HTTPS listener has been created and are listening on ports 5985 and 5986 respectively.
Verify Service Settings
+++++++++++++++++++++++
Once you have verified that WinRM is setup and listening on a port you can use ``winrm get winrm/config/service`` to get the configuration of the WinRM service::
#!powershell
PS C:\> winrm get winrm/config/service
Service
RootSDDL = O:NSG:BAD:P(A;;GA;;;BA)(A;;GR;;;IU)S:P(AU;FA;GA;;;WD)(AU;SA;GXGW;;;WD)
MaxConcurrentOperations = 4294967295
MaxConcurrentOperationsPerUser = 1500
EnumerationTimeoutms = 240000
MaxConnections = 300
MaxPacketRetrievalTimeSeconds = 120
AllowUnencrypted = false
Auth
Basic = true
Kerberos = true
Negotiate = true
Certificate = false
CredSSP = false
CbtHardeningLevel = Relaxed
DefaultPorts
HTTP = 5985
HTTPS = 5986
IPv4Filter = *
IPv6Filter = *
EnableCompatibilityHttpListener = false
EnableCompatibilityHttpsListener = false
CertificateThumbprint
AllowRemoteAccess = true
In the above example we are able to authenticate with the Windows host using:
- Basic (local accounts only)
- Kerberos (domain accounts only)
- Negotiate [Kerberos/NTLM] (local and domain accounts)
Because AllowUnencrypted is set to false we also have to use a HTTPS listener as pywinrm does not currently support encrypted WinRM messages over HTTP.
The following section defines the purpose of each relevant value::
* ``AllowUnencrypted``: When set to ``true`` allows WinRM messages to be sent without encryption.
* ``Auth/Basic``: Allows basic authentication, only for local accounts
* ``Auth/Kerberos``: Allows Kerberos authentication, only for domain accounts
* ``Auth/Negotiate``: Leverages Windows SSPI for auth, used by NTLM and Kerberos
* ``Auth/Certificate``: Allows certificate authentication, only for local accounts
* ``Auth/CredSSP``: Allows CredSSP authentication for credential delegation (double-hop). Not currently supported by pywinrm
* ``Auth/CbtHardeningLevel``: Channel Binding Token is either mandatory (``Strict``) or optional (``Relaxed``, ``None``). ``Strict`` not currently supported by pywinrm
.. note::
It is highly recommended to not set AllowUnencrypted to true, please
use HTTPS endpoints wherever possible.
Double-hop authentication is currently supported by pywinrm with
the Kerberos auth method. Please set ``ansible_winrm_kerberos_delegation=true``
in host vars for this.
