Laradock: how to enable/install php7 ldap support extension?

Question

I have set up docker with laradock.

I'm using the following package

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

I get the following error:

Call to undefined function Adldap\ldap_explode_dn()

Should I enter my docker workspace and try to install it?

docker-compose exec  workspace bash

How should I install it? Seems I can't find php7.0-ldap package from apt-get or apt-cache...

Is it possible to enable it through docker-compose or by editing someway one of docker files? (php-fpm/Dockerfile-70 ?

EDIT: (DockerFile-70 full contents with Solution provided)

Basically you need this in your php-fpm docker file:

RUN \
    apt-get update && \
    apt-get install libldap2-dev -y && \
    rm -rf /var/lib/apt/lists/* && \
    docker-php-ext-configure ldap --with-libdir=lib/x86_64-linux-gnu/ && \
    docker-php-ext-install ldap
