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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
