If you are enabling TLS/SSL-secured communications to the LDAP server (for example, when you configure the provider URL with ldaps: as done in LDAP_AUTH_PROVIDER_URL) some TLS negotiations will require that you provide a certificate in the key exchange process. To do that with LogScale you need to specify LDAP_AUTH_PROVIDER_CERT to be the PEM-format value of the certificate.

This is slightly more complicated when using Docker. See LDAP Authentication for more information.
