Synopsis

Add or remove LDAP attribute values.

Requirements

The below requirements are needed on the host that executes this module.

python-ldap

Parameters

Parameter	Choices/Defaults	Comments
bind_dn	Default: None	A DN to bind with. If this is omitted, we'll try a SASL bind with the EXTERNAL mechanism. If this is blank, we'll use an anonymous bind.
bind_pw	Default: None	The password to use with bind_dn.
dn required		The DN of the entry to modify.
name required		The name of the attribute to modify.
server_uri	Default: ldapi:///	A URI to the LDAP server. The default value lets the underlying LDAP client library look for a UNIX domain socket in its default location.
start_tls	Choices: yes no ←	If true, we'll use the START_TLS LDAP extension.
state	Choices: present ← absent exact	The state of the attribute values. If `present`, all given values will be added if they're missing. If `absent`, all given values will be removed if present. If `exact`, the set of values will be forced to exactly those provided and no others. If state=exact and value is empty, all values for this attribute will be removed.
validate_certs (added in 2.4)	Choices: yes ← no	If `no`, SSL certificates will not be validated. This should only be used on sites using self-signed certificates.
values required		The value(s) to add or remove. This can be a string or a list of strings. The complex argument format is required in order to pass a list of strings (see examples).

Notes

Note

This only deals with attributes on existing entries. To add or remove whole entries, see ldap_entry.
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.
For state=present and state=absent, all value comparisons are performed on the server for maximum accuracy. For state=exact, values have to be compared in Python, which obviously ignores LDAP matching rules. This should work out in most cases, but it is theoretically possible to see spurious changes when target and actual values are semantically identical but lexically distinct.

Examples

- name: Configure directory number 1 for example.com
  ldap_attr:
    dn: olcDatabase={1}hdb,cn=config
    name: olcSuffix
    values: dc=example,dc=com
    state: exact

# The complex argument format is required here to pass a list of ACL strings.
- name: Set up the ACL
  ldap_attr:
    dn: olcDatabase={1}hdb,cn=config
    name: olcAccess
    values:
      - >-
        {0}to attrs=userPassword,shadowLastChange
        by self write
        by anonymous auth
        by dn="cn=admin,dc=example,dc=com" write
        by * none'
      - >-
        {1}to dn.base="dc=example,dc=com"
        by dn="cn=admin,dc=example,dc=com" write
        by * read
    state: exact

- name: Declare some indexes
  ldap_attr:
    dn: olcDatabase={1}hdb,cn=config
    name: olcDbIndex
    values: "{{ item }}"
  with_items:
    - objectClass eq
    - uid eq

- name: Set up a root user, which we can use later to bootstrap the directory
  ldap_attr:
    dn: olcDatabase={1}hdb,cn=config
    name: "{{ item.key }}"
    values: "{{ item.value }}"
    state: exact
  with_dict:
    olcRootDN: cn=root,dc=example,dc=com
    olcRootPW: "{SSHA}tabyipcHzhwESzRaGA7oQ/SDoBZQOGND"

- name: Get rid of an unneeded attribute
  ldap_attr:
    dn: uid=jdoe,ou=people,dc=example,dc=com
    name: shadowExpire
    values: ""
    state: exact
    server_uri: ldap://localhost/
    bind_dn: cn=admin,dc=example,dc=com
    bind_pw: password

#
# The same as in the previous example but with the authentication details
# stored in the ldap_auth variable:
#
# ldap_auth:
#   server_uri: ldap://localhost/
#   bind_dn: cn=admin,dc=example,dc=com
#   bind_pw: password
- name: Get rid of an unneeded attribute
  ldap_attr:
    dn: uid=jdoe,ou=people,dc=example,dc=com
    name: shadowExpire
    values: ""
    state: exact
    params: "{{ ldap_auth }}"

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key	Returned	Description
modlist list	success	list of modified parameters Sample: [[2, "olcRootDN", ["cn=root,dc=example,dc=com"]]]

Status

This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
