Direction

Behavior

Both the provider and the requirer need to adhere to a certain set of criteria to be considered compatible with the ldap interface.

Sensitive information is transmitted through Juju Secrets rather than directly through the relation databag(s).

Provider

Is expected to use user and group provided by the requirer to create a bind DN in the DIT for the requirer to use for the bind operation. If the requirer does not provide user and group, the provider leverages requirer's Juju application name and model name.
Is expected to provide the requirer with necessary configuration for performing LDAP authentications and operations.
Is expected to update the application databag if any field's data is changed in the provider charmed application.

Requirer

Is expected to optionally provide user and group for the provider to generate the bind DN.
Is expected to consume the LDAP configuration data provided by the provider to configure the requirer's charmed application.

Relation Data

Provider

The provider provides LDAP URL, base DN, and bind DN, and LDAP authentication method for the requirer to connect and perform LDAP operations. It should be placed in the application databag.

Example

  relation-info:
    - endpoint: ldap
      related-endpoint: ldap
      application-data:
        urls: [ldap://ldap.canonical.com:3893, ldap://ldap.ubuntu.com:3893]
        base_dn: dc=canonical,dc=com
        bind_dn: cn=app,ou=model,dc=canonical,dc=com
        bind_password_secret: secret://59060ecc-0495-4a80-8006-5f1fc13fd783/cjqub6vubg2s77p3nio0
        auth_method: simple
        starttls: true

Requirer

The requirer provides LDAP client information. It should be placed in the application databag.

Example

  relation-info:
    - endpoint: ldap
      related-endpoint: ldap
      application-data:
        user: sssd
        group: machine-localhost
