1. Copy the following files from your repository clone to the indicated hosts:

    - **nginx-ldap-auth.conf** – NGINX Plus configuration file, which contains the minimal set of directives for testing the reference implementation. Install on the NGINX Plus host (in the **/etc/nginx/conf.d** directory if using the conventional configuration scheme). To avoid configuration conflicts, remember to move or rename any default configuration files installed with NGINX Plus.

    - **nginx-ldap-auth-daemon.py** – Python code for the ldap-auth daemon. Install on the host of your choice.

      Alternatively, use provided Dockerfile to build Docker image:

      ```

      docker build -t nginx-ldap-auth-daemon .

      docker run nginx-ldap-auth-daemon

     ```

    - **nginx-ldap-auth-daemon-ctl.sh** – Sample shell script for starting and stopping the daemon. Install on the same host as the ldap-auth daemon.

    - **backend-sample-app.py** – Python code for the daemon that during testing stands in for a real back-end application server. Install on the host of your choice.
