OpenSAML is a portable implementation of the Security Assertion Markup Language (SAML) standard for the formation and exchange of authentication, attribute, and authorization data using XML, as defined by OASIS. There are interfaces for a range of languages, including C++ and Java.
The Enterprise Sign On Engine (ESOE) allows an enterprise to meet its goals for identity management, single sign on, authorization, federation, and accountability for resource access in a very extensible manner. The ESOE is built using the OASIS SAML 2.0 specification, and the ESOE's powerful authorization engine is built around a reduced version of the OASIS XACML 2.0 standard called Lightweight eXtensible Authorization Control Markup Language or "LXACML".
mod_sesehe is an Apache module that disguises and removes the "Server: " HTTP header from responses. This allows you to hide certain information about the server. This also allows more accurate information to be provided if Apache is configured as a reverse proxy and a malformed request is received. Although sending the Server header in HTTP responses is not defined as a MUST in RFC 2616, the Apache HTTP Server does not otherwise allow you to disable sending this header via its configuration.
Shibboleth is a standards-based middleware software package providing Web single-sign-on across or within organizational boundaries. It implements standards such as OASIS' SAML to provide a federated single-sign-on and attribute exchange framework. It also provides extended privacy functionality, allowing the browser user and their home site to control the attributes released to each application.
GridShib is a glue layer that transparently binds a grid service provider such as the Globus Toolkit to a role-based authentication and access control system such as Shibboleth, so as to provide fine-grained access controls to members of virtual and physical organizations within a grid without having to distribute and synchronize information about individual users between those organizations.
