## 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 - | 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 added in 2.4 | 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 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 is deprecated in Ansible-2.7 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
      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
    #
    # In the example below, 'args' is a task keyword, passed at the same level as the module
    - name: Get rid of an unneeded attribute
      ldap_attr:
        dn: uid=jdoe,ou=people,dc=example,dc=com
        name: shadowExpire
        values: []
        state: exact
      args: "{{ 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"]]]
