Distributed Access Control System 1.4.20

Distributed Access Control System is a complete, light-weight, single sign-on and role-based access control system distributed under an open source license. It provides:
- extended authentication and role-based access control capabilities for Apache-based web services, CGI programs, and virtually any program or script;
- a wide array of flexible, modular, and efficient authentication methods, including two-factor authentication and hardware tokens;
- powerful, rule-based authorization checking that can be applied transparently to any resource or activity (such as web services, web content, and program features) by Apache-based web services and CGI programs, or virtually any program or script;
- an Apache 2.0/2.2 module, suite of CGI programs, and collection of command line tools for Unix-type platforms, such as Linux, FreeBSD, and Solaris.
Enhancements:
- This release includes an important bugfix to local_passwd_authenticate that prevents invalid passwords from being accepted.
- Some minor bugs have also been addressed, including some problems with dacs.quick(7).
