-/**
|
|
|
- * A clean-room implementation for Spring Security of an NTLM HTTP filter
|
|
|
- * leveraging the JCIFS library.
|
|
|
- * <p>
|
|
|
- * NTLM is a Microsoft-developed protocol providing single sign-on capabilities
|
|
|
- * to web applications and other integrated applications. It allows a web
|
|
|
- * server to automatically discover the username of a browser client when that
|
|
|
- * client is logged into a Windows domain and is using an NTLM-aware browser.
|
|
|
- * A web application can then reuse the user's Windows credentials without
|
|
|
- * having to ask for them again.
|
|
|
- * <p>
|
|
|
- * Because NTLM only provides the username of the Windows client, a Spring
|
|
|
- * Security NTLM deployment must have a <code>UserDetailsService</code> that
|
|
|
- * provides a <code>UserDetails</code> object with the empty string as the
|
|
|
- * password and whatever <code>GrantedAuthority</code> values necessary to
|
|
|
- * pass the <code>FilterSecurityInterceptor</code>.
|
|
|
- * <p>
|
|
|
- * The Spring Security bean configuration file must also place the
|
|
|
- * <code>ExceptionTranslationFilter</code> before this filter in the
|
|
|
- * <code>FilterChainProxy</code> definition.
