Parameters

Parameter

Comments

attrs

list / elements=string

A list of attributes for limiting the result. Use an actual list or a comma-separated string.

base64_attributes

list / elements=string

added in community.general 7.0.0

If provided, all attribute values returned that are listed in this option will be Base64 encoded.

If the special value * appears in this list, all attributes will be Base64 encoded.

All other attribute values will be converted to UTF-8 strings. If they contain binary data, please note that invalid UTF-8 bytes will be omitted.

bind_dn

string

A DN to bind with. If this is omitted, we’ll try a SASL bind with the EXTERNAL mechanism as default.

If this is blank, we’ll use an anonymous bind.

bind_pw

string

The password to use with bind_dn.

Default: ""

ca_path

path

added in community.general 6.5.0

Set the path to PEM file with CA certs.

client_cert

path

added in community.general 7.1.0

PEM formatted certificate chain file to be used for SSL client authentication.

Required if client_key is defined.

client_key

path

added in community.general 7.1.0

PEM formatted file that contains your private key to be used for SSL client authentication.

Required if client_cert is defined.

dn

string / required

The LDAP DN to search in.

filter

string

Used for filtering the LDAP search result.

Default: "(objectClass=*)"

page_size

integer

added in community.general 7.1.0

The page size when performing a simple paged result search (RFC 2696). This setting can be tuned to reduce issues with timeouts and server limits.

Setting the page size to 0 (default) disables paged searching.

Default: 0

referrals_chasing

string

added in community.general 2.0.0

Set the referrals chasing behavior.

anonymous follow referrals anonymously. This is the default behavior.

disabled disable referrals chasing. This sets OPT_REFERRALS to off.

Choices:

  • "disabled"

  • "anonymous" ← (default)

sasl_class

string

added in community.general 2.0.0

The class to use for SASL authentication.

Choices:

  • "external" ← (default)

  • "gssapi"

schema

boolean

Set to true to return the full attribute schema of entries, not their attribute values. Overrides attrs when provided.

Choices:

  • false ← (default)

  • true

scope

string

The LDAP scope to use.

subordinate requires the LDAPv3 subordinate feature extension.

children is equivalent to a “subtree” scope.

Choices:

  • "base" ← (default)

  • "onelevel"

  • "subordinate"

  • "children"

server_uri

string

The server_uri parameter may be a comma- or whitespace-separated list of URIs containing only the schema, the host, and the port fields.

The default value lets the underlying LDAP client library look for a UNIX domain socket in its default location.

Note that when using multiple URIs you cannot determine to which URI your client gets connected.

For URIs containing additional fields, particularly when using commas, behavior is undefined.

Default: "ldapi:///"

start_tls

boolean

If true, we’ll use the START_TLS LDAP extension.

Choices:

  • false ← (default)

  • true

validate_certs

boolean

If set to false, SSL certificates will not be validated.

This should only be used on sites using self-signed certificates.

Choices:

  • false

  • true ← (default)

xorder_discovery

string

added in community.general 6.4.0

Set the behavior on how to process Xordered DNs.

enable will perform a ONELEVEL search below the superior RDN to find the matching DN.

disable will always use the DN unmodified (as passed by the dn parameter).

auto will only perform a search if the first RDN does not contain an index number ({x}).

Choices:

  • "enable"

  • "auto" ← (default)

  • "disable"

Attributes

Attribute

Support

Description

check_mode

Support: full

Can run in check_mode and return changed status prediction without modifying target.

diff_mode

Support: none

Will return details on what has changed (or possibly needs changing in check_mode), when in diff mode.

Notes

Note

  • The default authentication settings will attempt to use a SASL EXTERNAL bind over a UNIX domain socket. This works well with the default Ubuntu install for example, which includes a cn=peercred,cn=external,cn=auth ACL rule allowing root to modify the server configuration. If you need to use a simple bind to access your server, pass the credentials in bind_dn and bind_pw.

Examples

- name: Return all entries within the 'groups' organizational unit.
  community.general.ldap_search:
    dn: "ou=groups,dc=example,dc=com"
  register: ldap_groups

- name: Return GIDs for all groups
  community.general.ldap_search:
    dn: "ou=groups,dc=example,dc=com"
    scope: "onelevel"
    attrs:
      - "gidNumber"
  register: ldap_group_gids
