Because of:
May 15 11:09:01 gw automount[20964]: attempting to mount entry /smb/xp0
May 15 11:09:01 gw automount[20964]: lookup_mount: lookup(file): looking
up xp0

and since this is executed during the lookup:

static int lookup_name_file_source_instance(struct autofs_point
*ap, 				struct map_source *map, const char *name, int name_len)
        struct map_source *instance;
        char src_file[] = "file";
        char src_prog[] = "program";
        time_t age = time(NULL);
        struct stat st;
        char *type, *format;

        if (stat(map->argv[0], &st) == -1) {
                warn(ap->logopt, "file map not found");
                return NSS_STATUS_NOTFOUND;
        }

        if (!S_ISREG(st.st_mode))
                return NSS_STATUS_NOTFOUND;

        if (st.st_mode & __S_IEXEC)
                type = src_prog;
        else
                type = src_file;

        format = map->format;
