GridSiteWiki

From GridSiteWiki

GridSiteWiki is a version of MediaWiki - the same software used by WikiPedia, but with user authentication based on X.509 certificates rather than usernames and passwords. (It is the basis of this Wiki, that you are currently reading.)

See the GridSiteWiki (http://www.gridsite.org/gridsitewiki/) page for an explanation of the software, full sources and a brief installation guide.
