- new : external authentication in another users table. Previous users table
is divided between users (common properties with any web application) and user_infos (phpwebgallery specific informations). External table and fields can be configured. - modification : profile.php is not reachable through administration anymore (not useful). - modification : in profile.php, current password is mandatory only if user tries to change his password. Username can't be changed. - deletion : of obsolete functions get_user_restrictions, update_user_restrictions, get_user_all_restrictions, is_user_allowed, update_user - modification : $user['forbidden_categories'] equals at least "-1" so that category_id NOT IN ($user['forbidden_categories']) can always be used. - modification : user_forbidden table becomes user_cache so that not only restriction informations can be stored in this table. git-svn-id: http://piwigo.org/svn/trunk@808 68402e56-0260-453c-a942-63ccdbb3a9ee
