autofs-5.1.9 - handle sss special case getautomntbyname() error From: Ian Kent The sss key lookup (via getautomntbyname()) returns EHOSTDOWN when the entry is invalid, such as when the location is empty. But setatomntent() has already been called successfully so we know the host is up and the map exists hence this probably should be EINVAL. In both these cases the better return is NSS_STATUS_UNAVAIL.
