Quick start tutorial

Attention

This tutorial will guide you into a minimal installation and configuration procedure. You need some prerequisites:

Root access to a Debian, Ubuntu, CentOS or RHEL test system
A web browser
A cup of coffee (or tea, we are open minded)

Installation

Debian / Ubuntu

apt install apt-transport-https
wget -O - https://lemonldap-ng.org/_media/rpm-gpg-key-ow2 | apt-key add -
echo "deb https://lemonldap-ng.org/deb stable main" > /etc/apt/sources.list.d/lemonldap-ng.list
apt update
apt install lemonldap-ng

CentOS / RHEL

curl https://lemonldap-ng.org/_media/rpm-gpg-key-ow2 > /etc/pki/rpm-gpg/RPM-GPG-KEY-OW2
echo '[lemonldap-ng]
name=LemonLDAP::NG packages
baseurl=https://lemonldap-ng.org/redhat/stable/$releasever/noarch
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-OW2' > /etc/yum.repos.d/lemonldap-ng.repo
yum update
yum install epel-release
yum install lemonldap-ng
# If you use SELinux
yum install lemonldap-ng-selinux

SSO domain configuration

LemonLDAP::NG needs all its components to be served on the same DNS domain.

If you can edit your /etc/hosts file or have access to a DNS server, check Using your own domain, if you have no way to modify your DNS configuration, check Using nip.io (or other DNS wildcard services).

Using your own domain

The defaut SSO domain is example.com. You can keep it for your tests or change it, for example for mydomain.com:

sed -i 's/example\.com/mydomain.com/g' \
   /etc/lemonldap-ng/* /var/lib/lemonldap-ng/conf/lmConf-1.json \
   /etc/nginx/conf.d/* \
   /etc/httpd/conf.d/* \
   /etc/apache2/sites-available/*

In order to be able to test, update your DNS or your local hosts file to map these names to the SSO server IP:

auth.mydomain.com
manager.mydomain.com
test1.mydomain.com
test2.mydomain.com

For example, you can enter the following command on your local computer: (adjust according to your server IP and test domain)

echo "192.168.1.30 auth.mydomain.com manager.mydomain.com test1.mydomain.com test2.mydomain.com" >> /etc/hosts

Using nip.io (or other DNS wildcard services)

If you cannot edit /etc/hosts or your DNS zone, don’t give up yet, you can use services such as nip.io, xip.io, sslip.io or others.

For example, if your server IP is 192.168.12.13, you can use 192-168-12-13.nip.io as your SSO domain:

sed -i 's/example\.com/192-168-12-13.nip.io/g' \
   /etc/lemonldap-ng/* /var/lib/lemonldap-ng/conf/lmConf-1.json \
   /etc/nginx/conf.d/* \
   /etc/httpd/conf.d/* \
   /etc/apache2/sites-available/*

Warning

nip.io, xip.io or any DNS wildcard services mentionned in this section are not affiliated with the LemonLDAP::NG project in any way. These services will receive DNS requests that will allow them to know your test server’s IP address. If this is an issue for you, do not use these services.

Run

Starting services

Debian / Ubuntu

Enable the Nginx virtualhosts and restart the web server and LemonLDAP::NG server to apply the configuration changes

cd /etc/nginx/sites-enabled
ln -s ../sites-available/*nginx* .
systemctl restart lemonldap-ng-fastcgi-server
systemctl restart nginx

CentOS / RHEL

Enable and start httpd

systemctl enable httpd
systemctl start httpd

Open SSO session

Go on http://auth.mydomain.com and log with one of the demonstration account.

Login	Password	Role
rtyler	rtyler	user
msmith	msmith	user
dwho	dwho	administrator

Access protected application

Try http://test1.mydomain.com or http://test2.mydomain.com

Edit configuration

Log with the dwho account and go on http://manager.mydomain.com
