Hi Alex. It appears older NTLM support was dropped in Linux Kernel, so SMB version 1.0 does not work for cifs mount. SMB version 2.0 still works though.
See https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=76a3c92ec9e0668e4cd0e9ff1782eb68f61a179c cifs: remove support for NTLM and weaker authentication algorithms for SMB1. This removes the dependency to DES.
