        # As implemented in nginx-ldap-auth-daemon.py, the ldap-auth daemon
        # communicates with a LDAP server, passing in the following
        # parameters to specify which user account to authenticate. To
        # eliminate the need to modify the Python code, this file contains
        # 'proxy_set_header' directives that set the values of the
        # parameters. Set or change them as instructed in the comments.
