ldapsearch is a handy tool that is part of open ldap. You can query some handy information out of our ldap servers as follows if you have an account to bind with:

Nginx doesn't support LDAP authentication with it's default modules, so a third-party module (https://github.com/kvspb/nginx-auth-ldap) is required. More information can be found here: http://deezx.github.io/blog/2015/04/24/how-to-configure-nginx-with-ldap-authentication/
This is not a good idea, since nginx-auth-ldap does not support STARTTLS encryption, only ldaps on port 636. A better option for those requiring nginx might be auth_pam, and pam/sssd configured to authenticate via AD. Do not use this configuration in production, or on off-site services. Only for use in development environments, authenticating with bob from the local PS1 network.
Building nginx 1.8.0 from source with LDAP support on Debian Jessie
apt-get remove nginx
apt-get install libldap2-dev libpcre3-dev build-essential
wget http://nginx.org/download/nginx-1.8.0.tar.gz
git clone https://github.com/kvspb/nginx-auth-ldap.git
tar -zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0

If you didn't have debian-packaged nginx installed previously, you will also want to install and configure an nginx init script/systemd service unit.
Configuring nginx:
* /etc/nginx/nginx.conf (add to http{} block)
