Overview

Use the OpenLDAP integration to get metrics from the cn=Monitor backend of your OpenLDAP servers.

Setup

Installation

The OpenLDAP integration is packaged with the Agent. To start gathering your OpenLDAP metrics:

Have the cn=Monitor backend configured on your OpenLDAP servers.
Install the Agent on your OpenLDAP servers.

Configuration

Prepare OpenLDAP

If the cn=Monitor backend is not configured on your server, follow these steps:

Check if monitoring is enabled on your installation:
```
 sudo ldapsearch -Y EXTERNAL -H ldapi:/// -b cn=module{0},cn=config
```
If you see a line with olcModuleLoad: back_monitor.la, monitoring is already enabled, go to step 3.

Enable monitoring on your server:

    cat <<EOF | sudo ldapmodify -Y EXTERNAL -H ldapi:///
    dn: cn=module{0},cn=config
    changetype: modify
    add: olcModuleLoad
    olcModuleLoad: back_monitor.la
    EOF

Create an encrypted password with slappasswd.

Add a new user:

    cat <<EOF | ldapadd -H ldapi:/// -D <YOUR BIND DN HERE> -w <YOUR PASSWORD HERE>
    dn: <USER_DISTINGUISHED_NAME>
    objectClass: simpleSecurityObject
    objectClass: organizationalRole
    cn: <COMMON_NAME_OF_THE_NEW_USER>
    description: LDAP monitor
    userPassword:<PASSWORD>
    EOF

Configure the monitor database:

    cat <<EOF | sudo ldapadd -Y EXTERNAL -H ldapi:///
    dn: olcDatabase=Monitor,cn=config
    objectClass: olcDatabaseConfig
    objectClass: olcMonitorConfig
    olcDatabase: Monitor
    olcAccess: to dn.subtree='cn=Monitor' by dn.base='<USER_DISTINGUISHED_NAME>' read by * none
    EOF

Configure the OpenLDAP integration

Host

To configure this check for an Agent running on a host:

Metric collection

Edit your openldap.d/conf.yaml in the conf.d folder at the root of your Agent’s configuration directory. See the sample openldap.d/conf.yaml for all available configuration options.

init_config:

instances:
  ## @param url - string - required
  ## Full URL of your ldap server. Use `ldaps` or `ldap` as the scheme to
  ## use TLS or not, or `ldapi` to connect to a UNIX socket.
  #
  - url: ldaps://localhost:636

    ## @param username - string - optional
    ## The DN of the user that can read the monitor database.
    #
    username: "<USER_DISTINGUISHED_NAME>"

    ## @param password - string - optional
    ## Password associated with `username`
    #
    password: "<PASSWORD>"

Restart the Agent.

Log collection

Available for Agent versions >6.0

Collecting logs is disabled by default in the Datadog Agent. Enable it in your datadog.yaml file:
```
logs_enabled: true
```
Add this configuration block to your openldap.d/conf.yaml file to start collecting your OpenLDAP logs:
```
logs:
  - type: file
    path: /var/log/slapd.log
    source: openldap
    service: "<SERVICE_NAME>"
```
Change the path and service parameter values and configure them for your environment. See the sample openldap.d/conf.yaml for all available configuration options.
Restart the Agent.

Containerized

Metric collection

For containerized environments, see the Autodiscovery Integration Templates for guidance on applying the parameters below.

Parameter	Value
`<INTEGRATION_NAME>`	`openldap`
`<INIT_CONFIG>`	blank or `{}`
`<INSTANCE_CONFIG>`	`{"url":"ldaps://%%host%%:636","username":"<USER_DISTINGUISHED_NAME>","password":"<PASSWORD>"}`

Log collection

Available for Agent versions >6.0

Collecting logs is disabled by default in the Datadog Agent. To enable it, see Kubernetes Log Collection.

Parameter	Value
`<LOG_CONFIG>`	`{"source": "openldap", "service": "<SERVICE_NAME>"}`

Validation

Run the Agent’s status subcommand and look for openldap under the Checks section.

Compatibility

The check is compatible with all major platforms.
