[CentOS] Can't see all files on a cifs mount

Awhile ago I've set up a backup of my C6 home server to a D-Link NAS and 
it seems to be working.
But when I mount a share with the backups I can't see files or 
directories not readable by others.
I'm not very knowledgeable in cifs and probably missing some obvious 
options.
noserverino option suggested on ubuntu forums didn't help.
TIA
