DirectSSO

SigSSO provides signature-based Web Single SignOn (SSO) across any boundaries. It does not require any common infrastructure but relies on a trust relationship from the SSO client applications to the SSO server (typically a web portal, but could also be a reverse proxy et al.)

SSO client applications are enabled by installation of a small adapter plus a generic agent that provides security means like signature validation, timnestamp and replay protection.

SSO supports single signon for variety of existing open source web applications.

SigSSO is licenced unter the terms of the GPL.
