Les d\u00e9veloppeurs du projet Matrix ont commis une erreur. affirment<\/a><\/noindex>, ce qui signifie que le probl\u00e8me ne se manifestait que dans la branche master \u00ab matrix-appservice-ldap3 \u00bb, et non dans les versions, mais dans le d\u00e9p\u00f4t, la ligne probl\u00e9matique est pr\u00e9sent<\/a><\/noindex> existe depuis 2016 (il est possible que les conditions d'exploitation du probl\u00e8me n'aient surgi qu'\u00e0 la suite de r\u00e9cents changements).<\/p>\n

Le package de services Librem One lanc\u00e9 n\u00e9cessite un abonnement payant (7,99 $ par mois ou 71,91 $ par an), mais les clients mobiles et les gestionnaires de serveurs se basent sur des projets open source existants qui ont \u00e9t\u00e9 renomm\u00e9s<\/a><\/noindex> pour \u00eatre distribu\u00e9s sous la marque Librem. Par exemple, Librem Chat est un client Matrix renomm\u00e9 Riot<\/a><\/noindex>, Librem Social est bas\u00e9 sur Tusky<\/a><\/noindex>, Librem Mail a \u00e9t\u00e9 renomm\u00e9 de K-9<\/a><\/noindex>, Librem Tunnel est d\u00e9riv\u00e9 de Ics-openvpn<\/a><\/noindex>. Les composants serveur sont bas\u00e9s sur
\n Postfix et Dovecot pour Librem Mail, Matrix<\/a><\/noindex> pour Librem Chat et Mastodon<\/a><\/noindex> pour Librem Social. La raison avanc\u00e9e pour fournir des applications sous d'autres noms est de vouloir rassembler sous une marque reconnue divers services d\u00e9centralis\u00e9s bas\u00e9s sur des standards ouverts (Matrix, ActivityPub, IMAP). <\/p>\n
