Subject: cifs: allow sec=none mounts to work against servers that don't support extended security
X-Git-Tag: next-20130527~81^2~8

cifs: allow sec=none mounts to work against servers that don't support extended security

In the case of sec=none, we're not sending a username or password, so
there's little benefit to mandating NTLMSSP auth. Allow it to use
unencapsulated auth in that case.
