我已经用laradock设置了docker.

我正在使用以下包

"adldap2/adldap2-laravel": "^2.1"

我收到以下错误：

Call to undefined function Adldap\ldap_explode_dn()

我应该进入我的docker工作区并尝试安装它吗？

docker-compose exec  workspace bash

我该如何安装？
好像我找不到apt-get或apt-cache的PHP7.0-ldap包……

是否可以通过docker-compose或通过编辑某个docker文件来启用它？ (PHP-fpm / Dockerfile-70？

编辑：(DockerFile-70全内容,提供解决方案)
