community.general.ldap_attr – Add or remove LDAP attribute values

Note

This plugin is part of the community.general collection.

To install it use: ansible-galaxy collection install community.general.

To use it in a playbook, specify: community.general.ldap_attr.

DEPRECATED

Removed in

version 3.0.0

Why

The current “ldap_attr” module does not support LDAP attribute insertions or deletions with objectClass dependencies.

Alternative

Use community.general.ldap_attrs instead. Deprecated in community.general 0.2.0.

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
string
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
string
The password to use with bind_dn.
dn
string / required
The DN of the entry to add or remove.
name
string / required
The name of the attribute to modify.
server_uri
string
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
boolean
    Choices:
  • no ←
  • yes
If true, we'll use the START_TLS LDAP extension.
state
string
    Choices:
  • absent
  • exact
  • present ←
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 an empty list, all values for this attribute will be removed.
validate_certs
boolean
    Choices:
  • no
  • yes ←
If set to no, SSL certificates will not be validated.
This should only be used on sites using self-signed certificates.
values
raw / 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 community.general.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.
  • The params parameter was removed due to circumventing Ansible’s parameter handling. The params parameter started disallowing setting the bind_pw parameter in Ansible-2.7 as it was insecure to set the parameter that way.

Examples

- name: Configure directory number 1 for example.com
  community.general.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
  community.general.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
  community.general.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
  community.general.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
  community.general.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
#
# In the example below, 'args' is a task keyword, passed at the same level as the module
- name: Get rid of an unneeded attribute
  community.general.ldap_attr:
    dn: uid=jdoe,ou=people,dc=example,dc=com
    name: shadowExpire
    values: []
    state: exact
  args: "{{ ldap_auth }}"

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

Key Returned Description
modlist
list / elements=string
