yum install http://mirror.de-labrusse.fr/NethDev/nethserver-moodle-0.0.10/nethserver-moodle-0.0.10-1.ns7.sdl.noarch.rpm
this new version allows the authentication of Nethserver users in Moodle following you have installed openldap or samba4 AD. Members of the group staff are granted as 'course creator'
One drawback, because moodle is an ogre, to do this feature I needed to import a database with the default password of admin -> password
administrator login : admin
administrator password : password
of course think to change it in the admin preference
If we don't want a default password, the only way I found is to install moodle, and at the end, after the database creation by the web page, then issue manually in the terminal a signal-event to INSERT our modifications...not fancy
