In backfire 10.03 RC6 all works fine..

You need to install kmod-crypto-md4. If it is not available yet you have to wait for an updated build.

sorry, did not see the prior closing and noting of duplicate. I am not sure how to delete my comment. Sorry

[John Thomas <openwrt-devel-2012@…>]

kmod-crypto-md4 is already installed, see below. Could the kernel update be the issue as mount.cifs works fine on 3.6.

​http://kernelnewbies.org/LinuxChanges notes the following about 3.7.1:
The CIFS networking filesystem has added support for the version 2 of the SMB protocol. The SMB2 protocol is the successor to the popular CIFS and SMB network file sharing protocols, and is the native file sharing mechanism for Windows operating systems since it was introduced in Windows Vista in 2006. SMB2 enablement will eventually allow users better performance, security and features, than would not be possible with previous protocols.
