Collect Red Hat Directory Server LDAP logs

Supported in:

Google secops SIEM

This document explains how to ingest Red Hat Directory Server LDAP logs to Google Security Operations using the Bindplane agent.

Red Hat Directory Server is an enterprise-class LDAP directory service built on open standards that provides centralized user identity management, authentication, and access control for Linux and UNIX environments. Directory Server stores access, error, audit, audit fail, and security logs in the /var/log/dirsrv/slapd-instance_name/ directory, recording client connections, LDAP operations, configuration changes, failed operations, and security events such as authentication attempts and authorization issues.

Before you begin

Make sure you have the following prerequisites:

A Google SecOps instance
A Linux host with systemd
Network connectivity between the Bindplane agent and the Red Hat Directory Server host
If running behind a proxy, ensure firewall ports are open per the Bindplane agent requirements
Root or sudo access to the Red Hat Directory Server host
Red Hat Directory Server 11 or later installed and running
The rsyslog service installed and running on the Directory Server host

Get a Google SecOps ingestion authentication file

Sign in to the Google SecOps console.
Go to SIEM Settings > Collection Agents.
Download the Ingestion Authentication File.
Save the file securely on the system where Bindplane will be installed.

Note: This JSON file contains credentials for authenticating the Bindplane agent to Google SecOps.

Get a Google SecOps customer ID

Sign in to the Google SecOps console.
Go to SIEM Settings > Profile.
Copy and save the Customer ID from the Organization Details section.

Note: The customer ID is required for configuring the Bindplane agent exporter.

Install the Bindplane agent

Install the Bindplane agent on your Linux operating system according to the following instructions.

Linux installation

Open a terminal with root or sudo privileges.

Run the following command:

sudo sh -c "$(curl -fsSlL https://github.com/observiq/bindplane-agent/releases/latest/download/install_unix.sh)" install_unix.sh

Wait for the installation to complete.
Verify the installation by running:
```
sudo systemctl status observiq-otel-collector
```
The service should show as active (running).

Additional installation resources

For additional installation options and troubleshooting, see the Bindplane agent installation guide.

Configure the Bindplane agent to ingest syslog and send to Google SecOps

Locate the configuration file

Linux:

sudo nano /opt/observiq-otel-collector/config.yaml

Edit the configuration file

Replace the entire contents of config.yaml with the following configuration:

receivers:
    udplog:
        listen_address: "0.0.0.0:514"

exporters:
    chronicle/redhat_ds:
        compression: gzip
        creds_file_path: '/etc/bindplane-agent/ingestion-auth.json'
        customer_id: '<customer_id>'
        endpoint: malachiteingestion-pa.googleapis.com
        log_type: REDHAT_DIRECTORY_SERVER
        raw_log_field: body

service:
    pipelines:
        logs/redhat_ds:
            receivers:
                - udplog
            exporters:
                - chronicle/redhat_ds

Configuration parameters

Replace the following placeholders:

Receiver configuration:
- udplog: The receiver type based on protocol:
  - udplog for UDP syslog
  - tcplog for TCP syslog
  - syslog for RFC 3164/5424 syslog
- 0.0.0.0: IP address to listen on:
  - 0.0.0.0 to listen on all interfaces (recommended)
  - Specific IP address to listen on one interface
- 514: Port number to listen on (for example, 514, 1514, 6514)
Exporter configuration:
- <customer_id>: Customer ID from the earlier step
- malachiteingestion-pa.googleapis.com: Regional endpoint URL:
  - US: malachiteingestion-pa.googleapis.com
  - Europe: europe-malachiteingestion-pa.googleapis.com
  - Asia: asia-southeast1-malachiteingestion-pa.googleapis.com
  - See Regional Endpoints for complete list
- Adjust the creds_file_path depending on the platform:
  - Linux: /etc/bindplane-agent/ingestion-auth.json

Save the configuration file

After editing, save the file:
- Linux: Press Ctrl+O, then Enter, then Ctrl+X

Restart the Bindplane agent to apply the changes

To restart the Bindplane agent in Linux, run the following command:

sudo systemctl restart observiq-otel-collector

Verify the service is running:

sudo systemctl status observiq-otel-collector

Check logs for errors:

sudo journalctl -u observiq-otel-collector -f

Enable audit and audit fail logging in Red Hat Directory Server

By default, Red Hat Directory Server enables access, error, and security logging, but disables audit and audit fail logging. Enable these logs to capture all directory changes and failed operations.

Open a terminal with root or sudo privileges on the Directory Server host.
Enable the audit log by running the following command:
```
dsconf -D "cn=Directory Manager" instance_name config replace nsslapd-auditlog-logging-enabled=on
```
Note: Replace instance_name with the actual name of your Directory Server instance.

Enable the audit fail log by running the following command:

dsconf -D "cn=Directory Manager" instance_name config replace nsslapd-auditfaillog-logging-enabled=on

Verify that all log types are enabled:

dsconf -D "cn=Directory Manager" instance_name config get nsslapd-accesslog-logging-enabled nsslapd-errorlog-logging-enabled nsslapd-auditlog-logging-enabled nsslapd-auditfaillog-logging-enabled nsslapd-securitylog-logging-enabled

Verify that the log files exist in the log directory:
```
ls -la /var/log/dirsrv/slapd-instance_name/
```
Note: You should see the following log files: access, errors, audit, security. The audit fail log writes to the same file as the audit log by default unless a separate path is configured using the nsslapd-auditfaillog attribute.

Optional: enable logging using the web console

Sign in to the Red Hat Directory Server web console.
Select the instance.
Go to Server > Logging.
Select the log type you want to enable (for example, Audit Log).
Enable the logging toggle for the selected log type.
Click Save Log Settings.

Configure rsyslog to forward Directory Server logs to the Bindplane agent

Red Hat Directory Server writes logs to files in /var/log/dirsrv/slapd-instance_name/ rather than to syslog directly. Use the rsyslog imfile module to monitor these log files and forward the entries to the Bindplane agent.

Create a new rsyslog configuration file for Directory Server log forwarding:
```
sudo nano /etc/rsyslog.d/rhds-forward.conf
```

Add the following content to the configuration file:

# Load the imfile module to read log files
module(load="imfile" PollingInterval="10")

# Monitor the access log
input(type="imfile"
    File="/var/log/dirsrv/slapd-instance_name/access"
    Tag="dirsrv-access"
    Severity="info"
    Facility="local6")

# Monitor the error log
input(type="imfile"
    File="/var/log/dirsrv/slapd-instance_name/errors"
    Tag="dirsrv-errors"
    Severity="err"
    Facility="local6")

# Monitor the audit log
input(type="imfile"
    File="/var/log/dirsrv/slapd-instance_name/audit"
    Tag="dirsrv-audit"
    Severity="info"
    Facility="local6")

# Monitor the security log
input(type="imfile"
    File="/var/log/dirsrv/slapd-instance_name/security"
    Tag="dirsrv-security"
    Severity="info"
    Facility="local6")

# Forward all Directory Server logs to the Bindplane agent
local6.* @BINDPLANE_IP:514

Verify the rsyslog configuration syntax:
```
sudo rsyslogd -N1
```
Restart the rsyslog service to apply the changes:
```
sudo systemctl restart rsyslog
```
Verify that Directory Server logs are being forwarded by checking the Bindplane agent logs:
```
sudo journalctl -u observiq-otel-collector -f
```
Note: Generate an LDAP operation (for example, run an ldapsearch query) to produce access log entries and confirm that the Bindplane agent is receiving events.
