Permission for UrBackup Folder FREENAS

That what i did but…

I added a new user
and i gave him permission to the share folder (CIFS)

and i still get no access to the share folder from windows
also if i do from the windows on the share folder “connect from other user”
and put the user i give him permission to access

after that i do what i sayed before
that i gave 777 permission
and after that i couled access

but after i gave the 777 permission and UrBackup do new in incremental or full backup
and it create new files and folder i cannot again access to the new ones that created

(it not take the parent folder permission - that what i think but why?)

what i do wrong
