These are the mount attempt results using a stock 3.12 kernel built with
the Ubuntu Trusty config. I am not well versed enough in the various
security mechanisms to know what should work.

mount sec=ntlmssp on WinPro8 success
mount sec=ntlmsspi on WinPro8 failure
mount sec=ntlmv2 on WinPro8 failure
mount sec=ntlmv2i on WinPro8 failure
mount sec=ntlmssp on iOS-10.8 success
mount sec=ntlmsspi on iOS-10.8 success
mount sec=ntlmv2 on iOS-10.8 failure
mount sec=ntlmv2i on iOS-10.8 failure
mount sec=ntlmssp on Linux-3.2 success
mount sec=ntlmsspi on Linux-3.2 failure
mount sec=ntlmv2 on Linux-3.2 success
mount sec=ntlmv2i on Linux-3.2 failure

The mount parameters used were '-o
noserverino,nounix,user=test,pass=test'. For example,

sudo mount -t cifs //10.0.0.182/test /tmp/mnt -o
noserverino,nounix,user=test,pass=test,sec=ntlmssp

The patched kernel produced identical results.
