What we do

DSS provides system implementation, project management, and consulting services related to:

DSS is responsible for the design and implementation of DACS (the Distributed Access Control System), an open source, light-weight single sign-on system that provides extended authentication and access control capabilities for Apache and web-based services. DACS web services and commands can be used by application software, scripts, server software, and CGI programs for authentication and authorization checking functionality. DACS is a key component of Canada's National Forest Information System (NFIS) and has been deployed by other governmental agencies, businesses, and projects (About DACS).

DSS provides complete technical support for DACS. Additional information about DACS is available at dacs.dss.ca.

DSS has also been involved in the design and implementation of the Dxstore Database System, an open source database for Linux, FreeBSD, and other systems. (This project is currently in hibernation.)

Open source software and technical papers

A variety of open source software is available. Although some of it is now very old, many packages continue to see regular use on a wide variety of platforms.

Some older technical papers on distributed databases, directory services, and other topics are also available.

About DSS

Incorporated in 1996 and privately-held, DSS can bring an uncommon amount of knowledge and experience to almost any distributed systems project, as is clear from the company's unusually varied list of specialties and exceedingly deep background in many areas.
