For the stable distribution (buster), this problem has been fixed in version 2.0.2+ds-7+deb10u5, this update provides fixed example configuration which needs to be integrated into Lemonldap::NG deployments based on Nginx.

We recommend that you upgrade your lemonldap-ng packages.

For the detailed security status of lemonldap-ng please refer to its security tracker page at: [link moved to references]");
