Synopsis

  • Add or remove multiple LDAP attribute values.

Requirements

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

  • python-ldap

Parameters

Parameter Choices/Defaults Comments
attributes
dictionary / required
The attribute(s) and value(s) to add or remove. The complex argument format is required in order to pass a list of strings (see examples).
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.
dn
string / required
The DN of the entry to add or remove.
ordered
boolean
    Choices:
  • no ←
  • yes
If yes, prepend list values with X-ORDERED index numbers in all attributes specified in the current task. This is useful mostly with olcAccess attribute to easily manage LDAP Access Control Lists.
referrals_chasing
string
added in 2.0.0 of community.general
    Choices:
  • disabled
  • anonymous ←
Set the referrals chasing behavior.
anonymous follow referrals anonymously. This is the default behavior.
disabled disable referrals chasing. This sets OPT_REFERRALS to off.
sasl_class
string
added in 2.0.0 of community.general
    Choices:
  • external ←
  • gssapi
The class to use for SASL authentication.
possible choices are external, gssapi.
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:
  • present ←
  • absent
  • exact
The state of the attribute values. If present, all given attribute values will be added if they're missing. If absent, all given attribute values will be removed if present. If exact, the set of attribute values will be forced to exactly those provided and no others. If state=exact and the attribute value is empty, 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.

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.

Examples

- name: Configure directory number 1 for example.com
  community.general.ldap_attrs:
    dn: olcDatabase={1}hdb,cn=config
    attributes:
        olcSuffix: 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_attrs:
    dn: olcDatabase={1}hdb,cn=config
    attributes:
        olcAccess:

            {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

# An alternative approach with automatic X-ORDERED numbering
- name: Set up the ACL
