You did look at the permissions the files had in the directory after they have
been created by staffuser?
I *suppose* the staffuser has the default umask of 022 which means no write
permissions for group "staff" ... and since the parent directory belongs to
"user", not "staffuser", no permission to modify/delete.
We still don't know if you have applied some "force create ..." stanzas to the
share in smb.conf or other directives to modify permissions.
