+module d'abstraction de l'authentification et de l'autorisation du code applicatif d'un site web
+
+[Site Web du Projet](http://absec.adninformatique.com/)
+
+Le projet dépend pour être compilé de
+
+* libpam_dev
+* libapr1-dev
+* libaprutil-dev
+* apache2-dev
+* libmysqlclient-dev
+
+Un script de compilation est disponible
+
+```bash
+compile.sh
+```
+
+Le projet consiste principalement en un module pour Apache 2.x ce module peut être compilé pour utiliser 
+
+l'authentification:
+* via les fichiers systèmes /etc/passwd, /etc/shadow, /etc/group
+* via l'utilisation de PAM
+
+les autorisations:
+* via le système de fichier (permissions unix) map url-fichier
+* via une base de donnée MySQL map url-entrée dans la bd
+
+l'authentification a une entête commune soit absec_authen.h
+et à l'étape de liaison (link) l'on utilise soit absec_etc ou absec_pam
+
+un outil de test pour l'un ou l'autre selon la liaison est disponible
+sous test_authen
+
+l'autorisation a une entête commune soit absec_auto.h
+et à l'étape de liaison (link) l'on utilise soit absec_fs ou absec_mysql
+
+un outil de test pour l'un ou l'autre selon la liaison est disponible
+sous test_auto
