如何启用/安装php7 ldap支持扩展

我已经用laradock设置了docker。

我正在使用下面的包

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

我得到以下错误:

Call to undefined function Adldap'ldap_explode_dn()

我应该进入我的docker工作空间并尝试安装它吗?

docker-compose exec  workspace bash

我应该如何安装它?似乎我无法从apt-get或apt-cache中找到php7.0-ldap包…

是否有可能通过docker-compose或通过编辑某个docker文件来启用它?(php-fpm/dockerfile - 70 ?

编辑:(DockerFile-70完整内容，提供解决方案)
