community.windows.laps_password lookup – Retrieves the LAPS password for a server.

Note

This lookup plugin is part of the community.windows collection (version 1.10.0).

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	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. Choices: no ← (default) yes
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. Choices: simple gssapi ← (default)
ca_cert aliases: cacert_file 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.
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. Choices: ldap ← (default) ldaps
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. Choices: no ← (default) yes
username string	Required when using auth=simple. The username to authenticate with. Recommended to use the username in the UPN format, e.g. username@DOMAIN.COM. 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. Choices: never allow try demand ← (default)

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

Hint

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
