Hi all,
I am trying to mount our DFS root using NTLMv2, but this fails when
resolving the DFS target. Surprisingly, when I use NTLM, it does work.
This fails:
# mount -t cifs //sox.local/company /mnt/bla/ -o
username=kouprie,dom=sox,sec=ntlmv2
This works:
# mount -t cifs //sox.local/company /mnt/bla/ -o
username=kouprie,dom=sox,sec=ntlm
I am using linux kernel 2.6.37-rc3 and cifs-utils 4.5-2.
I have keyutils 1.4 installed and configured correctly (obviously, since
it works when using sec=ntlm).
The domain is configured to "Send NTLMv2 response only. Refuse LM".

As you can see above, upcall tries to resolve "SOXSRV03\C", which is
obviously the hostname including the first letter of the share.
Does anyone know how I can fix this?
Best regards,
