Spring Security NTLM 3

As of version 3.X Spring Security doesn't include the NTLM extension anymore.

For the purpose of using NTLM authentication on Spring 3 projects, I migrated the 2.0.5 NTLM extension to the new version of Spring Security.

The full project sources are available here:
http://github.com/aloiscochard/spring-security-ntlm

I haven't took time fixing the following bugs found on version 2.0.5:
https://jira.springsource.org/browse/SEC-1003
https://jira.springsource.org/browse/SEC-1087

Download
You can download the spring-security-ntlm snapshot here:

Usage
Due to the fact that NTLM isn't integrated in new version of spring-security-core, you need to add a custom filter.
Here is a snippet describing briefly how to do that:
<bean id="ntlmFilter" class="org.springframework.security.ui.ntlm.NtlmAuthenticationFilter"><br /> <property name="authenticationManager" ref="authenticationManager" /><br /> <property name="retryOnAuthFailure" value="false" /><br /> </bean><br /> <br /> <bean id="nullRequestCacheAwareFilter" class="org.springframework.security.web.savedrequest.NullRequestCache"/><br /> <br /> <!-- HTTP configuration --><br /> <sec:http><br /> <sec:request-cache ref="nullRequestCacheAwareFilter"/><br /> <sec:custom-filter after="EXCEPTION_TRANSLATION_FILTER" ref="ntlmFilter"/><br /> <br /> <!-- ... your configuration here ... --><br /> <br /> </sec:http>Don't hesitate to ask if you need help, this extension work exactly as version 2.0.5. You can use an example from version 2.0.5 if you are starting from scratch.
