Are there any alternatives for JCIFS NTLM library?
To be honest, you should not look for one. For your SSO needs you should use proper kerberos / SPNEGO instead of the legacy NTLM.
For that stuff you need no special libraries as JVMs are already enabled for doing that automatically. All you have to do is to configure your application and JVM security policies properly. The official documentation from Sun should give you all the details you need, just browse the "security APIs" section.
