AppFusions' Kerberos SSO Authenticator for AD & Atlassian Servers is a single sign-on authenticator for Active Directory and includes service deployment for Confluence, JIRA, Stash, Crowd, FishEye/Crucible, Bamboo and (I believe) some more.
It uses Kerberos rather than NTLM. NTLM does not support any recent cryptographic methods – I believe NTLM is no longer recommended by Microsoft.
I'm told they've successfully deployed it 80 or more times and have some big enterprises using it, but you should ask AppFusions for details of that.
Just to be clear I absolutely agree with statement that NTLM shouldn't be used by any sane organization (though we see plenty of it in the wild). Our plugin does support NTLM as a fallback, but the primary technology/protocol is NTLMv2 - a very different beast. I have directed Alicia to a Kerberos plugin - there are several of them on the Atlassian Marketplace now. Since she is asking here, there must be something that doesn't fit her scenario in full.
I suggest you to elaborate on "cross platform" and "true" in this question.
Since you've already tried our EasySSO Single Sign-On for Confluence and based on our email discussions I suppose "cross-platform" means "supporting Apple OS X devices" but perhaps it's more than that?
So, auto-login just like ours but supporting Macs :) I wish browsers on Mac OS X would do NTLMv2.
