Auth MemCookie is an Apache v2 authentication and authorization module based on a cookie authentication mechanism. The module doesn't do authentication by itself, but verifies if the cookie used for authentication is valid for each URL protected by the module. The module also validates whether the authenticated user has authorization to access the URL. Authentication is done externally through an authentication form page, and all authentication information necessary to the module is a stored in memcached.
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".
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.
Sleutel is a multi-platform password manager that is written using the Eclipse Rich Client Platform (RCP). Its goal is to manage password/ID pairs for accessing Web sites and to provide an example RCP application. It features configurable password generation, labeling of password entries (a la GMail), an intuitive UI following the Eclipse model, merge capabilities, and the ability to track usage count and dates of password entries. Sleutel is the Dutch word for key.
libapache2-mod-scramble-ip is an Apache 2 module that works like mod_removeip, but instead of just overwriting the IP address with 127.0.0.1, it encrypts the IP address. This way you always get an IP address to work with (in scripts, etc.) and have the ability to use tools like awstats to analyze your logs. It's in alpha status, but working on some Apache 2 servers, and the 'cost' (load) should be small and reasonable.
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.
