Note

This plugin is part of the community.windows collection (version 1.7.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.windows.

To use it in a playbook, specify: community.windows.laps_password.

Synopsis

This lookup returns the LAPS password set for a server from the Active Directory database.
See https://github.com/jborean93/ansible-lookup-laps_password for more information around installing pre-requisites and testing.

Requirements

The below requirements are needed on the local controller node that executes this lookup.

python-ldap

Parameters

Parameter	Choices/Defaults	Comments
_terms string / required		The host name to retrieve the LAPS password for. This is the `Common Name (CN`) of the host.
allow_plaintext boolean	Choices: no ← yes	When set to `yes`, will allow traffic to be sent unencrypted. It is highly recommended to not touch this to avoid any credentials being exposed over the network. Use `scheme=ldaps`, `auth=gssapi`, or `start_tls=yes` to ensure the traffic is encrypted.
auth string	Choices: simple gssapi ←	The type of authentication to use when connecting to the Active Directory server When using `simple`, the username and password options must be set. If not using `scheme=ldaps` or `start_tls=True` then these credentials are exposed in plaintext in the network traffic. It is recommended ot use `gssapi` as it will encrypt the traffic automatically. When using `gssapi`, run `kinit` before running Ansible to get a valid Kerberos ticket. You cannot use `gssapi` when either `scheme=ldaps` or `start_tls=True` is set.
ca_cert string		The path to a CA certificate PEM file to use for certificate validation. Certificate validation is used when `scheme=ldaps` or `start_tls=yes`. This may fail on hosts with an older OpenLDAP install like MacOS, this will have to be updated before reinstalling python-ldap to get working again. aliases: cacert_file
domain string / required		The domain to search in to retrieve the LAPS password. This could either be a Windows domain name visible to the Ansible controller from DNS or a specific domain controller FQDN. Supports either just the domain/host name or an explicit LDAP URI with the domain/host already filled in. If the URI is set, port and scheme are ignored.
password string		The password for `username`. Required when `username` is set.
port integer		The LDAP port to communicate over. If kdc is already an LDAP URI then this is ignored.
scheme string	Choices: ldap ← ldaps	The LDAP scheme to use. When using `ldap`, it is recommended to set `auth=gssapi`, or `start_tls=yes`, otherwise traffic will be in plaintext. The Active Directory host must be configured for `ldaps` with a certificate before it can be used. If kdc is already an LDAP URI then this is ignored.
search_base string		Changes the search base used when searching for the host in Active Directory. Will default to search in the `defaultNamingContext` of the Active Directory server. If multiple matches are found then a more explicit search_base is required so only 1 host is found. If searching a larger Active Directory database, it is recommended to narrow the search_base for performance reasons.
start_tls boolean	Choices: no ← yes	When `scheme=ldap`, will use the StartTLS extension to encrypt traffic sent over the wire. This requires the Active Directory to be set up with a certificate that supports StartTLS. This is ignored when `scheme=ldaps` as the traffic is already encrypted.
username string		Required when using `auth=simple`. The username to authenticate with. Recommended to use the username in the UPN format, e.g. `[email protected]`. This is required when `auth=simple` and is not supported when `auth=gssapi`. Call `kinit` outside of Ansible if `auth=gssapi` is required.
validate_certs string	Choices: never allow try demand ←	When using `scheme=ldaps` or `start_tls=yes`, this controls the certificate validation behaviour. `demand` will fail if no certificate or an invalid certificate is provided. `try` will fail for invalid certificates but will continue if no certificate is provided. `allow` will request and check a certificate but will continue even if it is invalid. `never` will not request a certificate from the server so no validation occurs.

Notes

Note

If a host was found but had no LAPS password attribute ms-Mcs-AdmPwd, the lookup will fail.
Due to the sensitive nature of the data travelling across the network, it is highly recommended to run with either auth=gssapi, scheme=ldaps, or start_tls=yes.
Failing to run with one of the above settings will result in the account credentials as well as the LAPS password to be sent in plaintext.
Some scenarios may not work when running on a host with an older OpenLDAP install like MacOS. It is recommended to install the latest OpenLDAP version and build python-ldap against this, see https://keathmilligan.net/python-ldap-and-macos for more information.

Examples

# This isn't mandatory but it is a way to call kinit from within Ansible before calling the lookup

  expect:
    command: kinit [email protected]
    responses:
      (?i)password: SecretPass1
  no_log: True

- name: Get the LAPS password using Kerberos auth, relies on kinit already being called
  set_fact:
    ansible_password: "{{ lookup('community.windows.laps_password', 'SERVER', domain='dc01.ansible.com') }}"

- name: Specific the domain host using an explicit LDAP URI
  set_fact:

- name: Use Simple auth with LDAP and StartTLS
  set_fact:
    ansible_password: "{{ lookup('community.windows.laps_password', 'app01',
                                 domain='dc01.ansible.com',

- name: Set certificate file to use when validating the TLS certificate
  set_fact:
    ansible_password: "{{ lookup('community.windows.laps_password', 'windows-pc',
                                 domain='dc01.ansible.com',
