Remote Mount - SMB drive - CIFS VFS: SMB signature verification returned error = -13

Hi,
I installed "Remote Mount" plugin, added and SMB share, it appears in /media/xxxxxxxxxxx folder and works fine. I'm using Raspberry pi2.
The problem is these log lines that started when I configured the remote share.

Mar 29 01:41:11 raspberrypi kernel: [31833.855657] CIFS VFS: SMB signature verification returned error = -13
Mar 29 01:41:11 raspberrypi kernel: [31833.864898] CIFS VFS: SMB signature verification returned error = -13
Mar 29 01:41:11 raspberrypi kernel: [31833.874336] CIFS VFS: SMB signature verification returned error = -13

Any hints?

I don't know why but adding users restriction on the system publishing the SMB share and configuring them in OMV solved the issue
