Disable signature when using LDAP
I've got the feeling that users inside the same organization (ie. able to login via LDAP) are able to share files without using Lufi.
So adding the "Share your files in total privacy on" signature at the bottom of mails (cf. themes/default/templates/partial/mail.js.ep#L.48) is not indicated. Because recipient (being an external person) may click the link and won't be able to login → frustration.
PS: Standard mail signature separator is not
-- (dash dash space) ;-)
