community.windows.laps_password – Retrieves the LAPS password for a server.¶
Note
This plugin is part of the community.windows collection (version 1.3.0).
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 | Configuration | 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
|
|
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
|
|
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
|
|
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
|
|
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
|
|
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
, orstart_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
- name: call kinit to retrieve Kerberos token
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:
ansible_password: "{{ lookup('community.windows.laps_password', 'SERVER', domain='ldap://ansible.com:389') }}"
- name: Use Simple auth over LDAPS
set_fact:
ansible_password: "{{ lookup('community.windows.laps_password', 'server',
domain='dc01.ansible.com',
auth='simple',
scheme='ldaps',
username='[email protected]',
password='SuperSecret123') }}"
- name: Use Simple auth with LDAP and StartTLS
set_fact:
ansible_password: "{{ lookup('community.windows.laps_password', 'app01',
domain='dc01.ansible.com',
auth='simple',
start_tls=True,
username='[email protected]',
password='SuperSecret123') }}"
- name: Narrow down the search base to a an OU
set_fact:
ansible_password: "{{ lookup('community.windows.laps_password', 'sql10',
domain='dc01.ansible.com',
search_base='OU=Databases,DC=ansible,DC=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',
start_tls=True,
ca_cert='/usr/local/share/certs/ad.pem') }}"
Return Values¶
Common return values are documented here, the following are the fields unique to this lookup:
Key | Returned | Description |
---|---|---|
_raw
string
|
success |
The LAPS password(s) for the host(s) requested.
