WIN2000 with NTLMv2 required gets SEGV in samba4 libwinregistry

[Matt Cobb]

I'm getting a SEGV when trying to connect to an IPC on a Win2000 box
that requires NTLMv2.  I'm using samba4.  Attached is the network trace.
As soon as it gets the ntlmssp challenge, it goes down.  Is this a known
problem?
