Merge branch 'master' into dist/eole/2.6.2/master

We need to provide what EoleSSO provides.

For me this 3 new template have to be placed in a dedicated package
like eole-sso-client, this templates are not necessary for the server
only usefull for the clients.

 * Add the lemonldap-ng deb respository we need the last version of LemonLDAP.

+#### Cadoles Repository
+* deb [ arch=all  ] https://vulcain.cadoles.com 2.6.2-dev main
+* Key URL : https://vulcain.cadoles.com/cadoles.gpg
+
+### Install packages
+
+apt update
+apt install eole-lemonldap
+
+### Configure LemonLDAP in GenConfig
+
+* Enable lemonldap in "Services" tab
+
+Gen_Config -> Services ->  Activer LemonLDAP::NG -> "Oui"
+
+* Fill LemonLDAP configuration
+
+#### Nginx Web case
+
+By default NGINX is configured to serve "web" application, in this case the lemonLDAP::NG application will
+not be served properly, so we need to disable this function
+
+GenConfig -> Services -> Activer la publication d’applications web par Nginx -> "Non'
+
+#### Configuration DNS
+* GenConfig -> Lemonldap -> Nom DNS du manager LemonLDAP-NG
+* GenConfig -> Lemonldap -> Nom DNS du service d'authentification LemonLDAP-NG
+
+#### Configuration LDAP
+* GenConfig -> Lemonldap -> Protocole LDAP à utiliser
+* GenConfig -> Lemonldap -> Adresse du Serveur LDAP utilisé par LemonLDAP::NG
+* GenConfig -> Lemonldap -> Port d'écoute du LDAP utilisé par LemonLDAP::NG
+* GenConfig -> Lemonldap -> Base DN des utilisateurs dans l'annuaire
+* GenConfig -> Lemonldap -> Utilisateur de connection à l'annuaire (DN ex: cn=reader,o=gouv,c=fr)
+* GenConfig -> Lemonldap -> Mot de passe de l'utilisateur de connection à l'annuaire (file like /root/.reader or the clear password)
+
+#### Configuration CAS
+
+Add your CAS attributes mapping ( uid = uid and mail = mail are created by default)
+
+* GenConfig -> Lemonldap -> Nom de l'attribut CAS
+* GenConfig -> Lemonldap -> Attribut LDAP équivalent
+
+### SSL issues
+
+If you use "autosign" certificates you need to add the "manager" and "auth" service names to the alternative names.
+You also need to include "reload" service name (available in GenConfig -> Mode Expert -> Lemonldap -> Nom DNS du service Reload de LemonLDAP-NG)
+
+* GenConfig -> Mode Expert -> Certificats ssl -> Nom Alternatif de la machine (SubjectAltName)
+
+If you use "manual" certificates make sure this names are covered by your SSL Certificate
+
+If you use "letsencrypt" mode you also need to add this names to the let'sencrypt request:
+
+* GenConfig -> Mode Expert -> Certificat ssl -> Nom de domaines supplémentaires
