title: Laradock: how to enable/install php7 ldap support extension?
body: <p>I have set up docker with laradock.</p>
  
  <p>I'm using the following package </p>
  
  <pre><code>"adldap2/adldap2-laravel": "^2.1"
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>Call to undefined function Adldap\ldap_explode_dn()
  </code></pre>
  
  <p>Should I enter my docker workspace and try to install it? </p>
  
  <pre><code>docker-compose exec  workspace bash
  </code></pre>
  
  <p>How should I install it?
  Seems I can't find php7.0-ldap package from apt-get or apt-cache...</p>
  
  <p>Is it possible to enable it through docker-compose or by editing someway one of docker files? (php-fpm/Dockerfile-70 ?</p>
  
  <p><strong>EDIT: (DockerFile-70 full contents with Solution provided)</strong></p>
