[Samba] mount cifs

Hi lists at merit.unu.edu,

I've had a call from a client yesterday who had issue with his copiers' 
scan2folder feature after badlock samba file server upgrade. The 
mount.cifs ntlm basic auth was not working either, and we had to 
configure "server signing=disabled" as a temporary workaround. Could you 
try that?

Cheers,

Denis
