Forward Authentication for use with proxies (caddy, nginx, traefik, etc)

## Usage
- Create a new folder, navigate to it in a commandprompt and run the following command:  
  `git clone https://code.spamasaurus.com/djpbessems/lucidAuth.git`  
- Edit `include/lucidAuth.config.php.example` to reflect your configuration and save as `include/lucidAuth.config.php`  
- Create a new website (within any php-capable webserver) and make sure that the documentroot points to the `public` folder  
- Check if you are able to browse to `https://<fqdn>/lucidAuth.login.php` (where `<fqdn>` is the actual domain -or IP address- your webserver is listening on)  
- Edit your proxy's configuration to use the new website as forward proxy:  
  #### ~~in Caddy/nginx~~    <small>(planned for a later stage)</small>

  #### in Traefik  
  Add the following lines (change to reflect your existing configuration):  
  ##### 1.7  
  ```
  [frontends.server1]
    entrypoints = ["https"]
    backend = "server1"
    [frontends.server1.auth.forward]
      address = "https://<fqdn>/lucidAuth.validateRequest.php"
    [frontends.server1.routes]
      [frontends.server1.routes.ext]
        rule = "Host:<fqdn>"
  ```
  ##### 2.0  
  Either whitelist IP's which should be trusted to send `HTTP_X-Forwarded-*` headers, ór enable insecure-mode in your static configuration:  
  ```
  entryPoints:
    https:
      address: :443
      forwardedHeaders:
        trustedIPs:
          - "127.0.0.1/32"
          - "192.168.1.0/24"
  #      insecure: true
  ```
  Define a middleware that tells Traefik to forward requests for authentication in your dynamic file provider:  
  ```
  https:
    middlewares:
      ldap-authentication:
        forwardAuth:
          address: "https://<fqdn>/lucidAuth.validateRequest.php"
          trustForwardHeader: true
  ```
  And finally add the new middleware to your service (different methods; this depends on your configuration):  
  ```
  # as a label (when using Docker provider)
  traefik.http.routers.router1.middlewares: "ldap-authentication@file"
  # as yaml (when using file provider)
  routers:
    router1:
      middlewares:
        - "ldap-authentication"
  ```

- #### Important!  
  The domainname of the website made in step 3, needs to match the domainname (*ignoring subdomains, if any*) of the resource utilizing this authentication proxy.
