LinOTP is a solution for strong two-factor authentication with one time passwords. It features a modular architecture into which UserIdResolver, authentication, and OTP calculation modules can be plugged. It includes UserIdResolver modules for LDAP/AD, SQL, and flat file user databases, and authentication modules for PAM and RADIUS. New modules can be developed easily. Supported tokens are HMAC-OTP/HOTP (RFC 4226/ OATH compliant), Aladdin eToken PASS, eToken NG-OTP, Safeword Alpine, Yubikey, Google Authenticator, motp, SMS OTP/Mobile TAN, and a Simple Pass token for users without token hardware. TOTP is supported, along with a new algorithm for daily passwords for applications not supporting RADIUS. CLI, Web, and GTK+ GUI clients are available for management. LinOTP features multi-client capability, redundancy, and a self-service portal. It has been used with PAM for local and SSH logins, Apache, VPN, and Windows Terminal Server, and is OATH certified.
YAMIdentd aims at being a simple, small, and functional ident daemon that can both process local requests and forward requests triggered by masqueraded hosts (when it is running on a Linux gateway). It currently only runs on Linux (2.4 and 2.6, 2.2 untested). The daemon can forward to any ident daemon that accepts forwarded requests. The code aims at being stable, fast, and RFC 1413 compliant. It is meant to be run from inetd. It doesn't use any configuration file. It should do the right thing automagically.
LemonLDAP::NG is a modular Web SSO based on Apache::Session modules. It simplifies the building of a protected area with a few changes in the application. It manages both authentication and authorization and provides headers for accounting, so you can have full AAA protection for your Web space. LemonLDAP::NG is a complete rewrite of LemonLDAP. All components needed to use it and to administer it are included in the tarball. However, all modules developed for LemonLDAP may not work with LemonLDAP::NG.
SMRadius is a high performance pre-forked RADIUS AAA server. It features a highly configurable backend engine supporting flexible data specifications. Its primary goal is to provide an extremely flexible authentication platform which may serve a large number of industries, including ISPs and WiSPs.
Sphirewall is a user-centric analytical network firewall/router. Out-of-the box, it provides user authentication coupled with powerful analytics which provide you with complete control over your network and users. With Sphirewall, you can manage and understand what is happening on your network with features such as qos, bandwidth quotas, user authentication, and much more. Not built on iptables, it is able to do things which other Open Source firewalls can't. Its very flexible, and with its open JSON API, can easily be plugged into any existing environment.
Collax Business Server is an all-in-one Linux server for small- and medium-sized businesses. It delivers all the important network services within a heterogeneous business environment for communication, infrastructure, compliance, groupware, and storage, all in a reliable and secure way which is easy to manage. It also provides essential security functions such as firewalling and virus and spam filtering, to protect against hacker attacks, viruses, and unsolicited email messages.
Multi-OTP is a PHP class that can be used to authenticate and manage OTP user tokens for strong two-factor authentication. It can create, update, and delete tokens to authenticate users with one time passwords (OTP). The users' data are stored in files. The class can also check the user token using several algorithms: Mobile OTP (MOTP), OATH/HOTP (RFC 4226), and OATH/TOTP HOTP Time Based (RFC 4226 extension). It works with compatible software tokens (iPhone, Android, PalmOS, Nokia, and other Java J2ME capable phones) and hardware tokens (such as Feitian, ZyXEL, Authenex, or Seamoon). The multiotp command line utility is also provided, both in "compiled" form (for Windows) and in source code (for Linux or educational purpose). The multiotp command line can be combined with FreeRADIUS (under Linux) or the free TekRADIUS LT (under Windows) in order to have a powerful radius strong authentication server.
M-Pin Strong Authentication System enables true two-factor authentication for Web sites and applications, based on the open source M-Pin Authentication Server and M-Pin Managed Service. The M-Pin Managed Service is a highly available, fault tolerant software as a service that issues cryptographic secrets to M-Pin Authentication Servers and Clients. The M-Pin Authentication Server uses just one leak-proof cryptographic key, and can't reveal any information about your users such as identity or login details, even if the key is compromised. The M-Pin Client is an HTML5 browser, so developers can easily integrate M-Pin into their Web sites and applications, enabling frictionless two-factor authentication and removing all username / password vulnerabilities.
libbadger is an alternative to existing decentralized authentication systems which require regular direct communication between client and authority. Badger allows clients to authenticate with servers easily and securely in a browserless environment because there is no necessity to tunnel the client to an authority for the purposes of its own authentication. Using Badger, clients only need to communicate with an authority once in their lifetimes.
