Here are the 3 sentenses in the Welcome page that need to be redone :

For internal Users, simply create a new user at the Users page
    If you chose to use LDAP authentication then you must provide connection details for your authentication provider on LDAP page
    For Roles and permissions, see the Roles page

Actually <Users> <LDAP> and <Roles> are links. "page" is not a member of the previous string so I cannot place the word "page" before the link as I should in French.
