SIP Servlets and authentication

[Asbjorn Grandt]

Hi

I need a little help with custom authentication when using SIP Servlets.
I'm pretty much chasing my own tail, and need a bone to point me in the
right direction.

I were hoping the samba jCIFS project would be able to help me get NTLM
authentication up and running on Sip Servlets, but that have given me a
whole new definition of headaches.
Not that ntlm-java ( http://code.google.com/p/ntlm-java/ ) were much better.

The problem is that I have to be able to connect to a Microsoft Lync
server, but not just from within it's domain (where Kerberos would be
the authenticator of choice, not that I would have any better idea of
implementing that), meaning that the only authentication available is
the NTLM.

I think the solution is to implement a custom Authenticator, which Sip
Servlets would then use when initiating a session.
But how?

Cheers

Sorry for the late reply here

The current authentication mechanisms defined by the Sip Servlets Spec ie SIP Digest and Identity, was not meant to be extensible (see SipSecurityUtils class) so you would need to add the NTLM auth there or make it extensible.

We would be interested in that contribution if you get it to work. So let me know if we can assist further somehow.
