Answer 1

Spring Security 2 supports NTLM, if you can´t upgrade the library try Jespa.

Some of the things that you can do with Jespa include:

• Implement NTLM Single Sign-On (SSO) for HTTP servers
• Check Windows group membership
• Enable NTLM authentication with AD using a JAAS LoginModule
• Add NTLM to the builtin HTTP stack or another HTTP client
• Use NTLM with SASL clients and SASL servers
• Add NTLM to the standard JNDI LDAP client
• Easily authenticate and encrypt network communication
• Create advanced and custom solutions using our intuitive "security provider" API

Answer 2

Here's another open source library, http://spnego.sourceforge.net, that can support integrated windows authentication/sso (no prompt).

The library is installed as a servlet filter.
