If the LDAP server has a self-signed SSL certificate

The instructions are relevant only for VMmanager 6 version 2025.05.1-1 or newer.

If an SSL connection is required to connect to LDAP and a self-signed SSL certificate is installed on the server, the connection will fail.

To avoid connection errors, perform the following steps before configuring synchronization:

  1. Connect to the server with the platform via SSH. For more information about connecting via SSH, see Workstation setup.
  2. Create a directory for LDAP configuration: 

    mkdir /opt/ispsystem/ldap
  3. Create an ldap.conf file in the /opt/ispsystem/ldap/ directory with the following content:

    TLS_CACERT	/etc/ssl/certs/ca-certificates.crt
    TLS_REQCERT never
  4. Create a patch file /opt/ispsystem/ldap.yaml with the following content:

    version: "3.7"
    services:
      auth_back4:
        volumes:
        - /opt/ispsystem/ldap/:/etc/ldap/
  5. Apply the patch to the LDAP service: 

    /usr/local/bin/vm add-patch -p=LDAP -f /opt/ispsystem/ldap.yaml
If this patch was installed on a server with VMmanager 6 version 2025.04.3 or older, it will block the updade to the latest version. To resolve this error and update the platform, follow the instructions in the Update article.

After completing these steps, configure the synchronization according to the instructions in the article Synchronization with the LDAP directory.
