Grails - Plugin: NTLM HTTP Authentication

Grails - Plugin: NTLM HTTP Authentication: "Sometimes, the requirement for web applications on corporate network is to provide a Single Sign On (SSO) functionality by using NTLM authentication and session security protocols. Microsoft Internet Explorer and Firefox (after some tweaking) have the ability to negotiate NTLM password hashes over an HTTP session thus relieving the user from entering username and password if their workstation is a member of the domain.

This plugin provides such functionality by creating a filter that authenticate users against a domain."
