Resolve LDAP SSL Certificate Errors During User Analytics Imports

Introduction

User Analytics imports that authenticate against LDAP may suddenly begin failing even though the configuration previously worked without issue. This commonly occurs after Active Directory certificate renewals or Public Key Infrastructure (PKI) changes.

This guide documents a troubleshooting process that resolved LDAP SSL validation errors after updated certificates were deployed within the Active Directory environment.

Symptoms

User Analytics LDAP imports begin failing unexpectedly.

LDAP previously worked for days or weeks before failing.

SSL or certificate validation errors appear during the import.

LDAP connections fail despite valid credentials.

An error similar to the following may be displayed:

Failed (Connection error: socket ssl wrapping error...

certificate ... doesn't match any name in ['<ipAddress>']

Cause

During troubleshooting, three separate issues were identified:

The Active Directory Root Certificate Authority had been renewed.
An Intermediate Certificate Authority had also been updated.
QRadar was configured to connect to the LDAP server by IP address, while the renewed certificate was issued to the server’s Fully Qualified Domain Name (FQDN).

Any one of these issues can cause SSL validation failures.

Resolution

Verify the LDAP Server Address

Review the LDAP configuration used by User Analytics.

If the LDAP server is configured using an IP address, replace it with the server’s Fully Qualified Domain Name (FQDN).

Field Note

The renewed certificate no longer contained the LDAP server’s IP address. Updating the LDAP configuration to use the FQDN immediately resolved the hostname validation error.

Update the Trusted Certificate Authorities

If your Active Directory certificate hierarchy has recently changed, export the following certificates from the domain environment:

Root Certificate Authority
Intermediate Certificate Authority

Copy the certificates to the QRadar Console.

Copy the certificates into the trusted certificate directory.

cp <certificate>.cer /etc/pki/ca-trust/source/anchors/

Update the system trust store.

update-ca-trust

Restart Docker so the updated trust store is available to QRadar applications.

systemctl restart docker

Reference

IBM provides additional guidance for updating trusted certificates:

Verify the Updated Certificates

List the running QRadar applications.

/opt/qradar/support/recon ps

Connect to the User Analytics container.

/opt/qradar/support/recon connect <container_id>

Verify the updated certificates are present inside the container.

ls -l /etc/pki/ca-trust/source/anchors/

Confirm that the newly imported Root and Intermediate CA certificates are available.

Verification

After completing the changes:

Verify the LDAP server is configured using its FQDN.
Confirm the new Root CA is installed.
Confirm the new Intermediate CA is installed.
Verify the certificates are present inside the User Analytics container.
Run a User Analytics import.
Confirm the LDAP import completes successfully without SSL validation errors.

If the Problem Persists

If LDAP imports continue to fail:

Verify the certificate presented by the LDAP server matches the configured hostname.
Confirm the complete certificate chain is trusted.
Check whether additional intermediate certificates are required.
Verify the LDAP server certificate has not expired.
Review the User Analytics application logs for additional SSL or LDAP errors.
