## Description
### Reproduce:
```sql
create device template t1 aligned (temperature FLOAT encoding=Gorilla,
status BOOLEAN encoding=PLAIN);
show device templates;
show nodes in device template t1;
set device template t1 to root.sg.aligned_template;
show paths set device template t1;
create timeseries using device template on root.sg.aligned_template;
show paths using device template t1;
insert into root.sg.aligned_template(time,temperature,status)
values(1,20,false),(2,22.1,true),(3,18,false);
CREATE USER user03 'pass1234';
LIST PRIVILEGES OF USER `user03`;
GRANT READ_DATA ON root.sg.aligned_template.temperature TO USER user03;
```
then log in with user03:
```sql
[root@xzh-97 iotdb-enterprise-1.3.2-SNAPSHOT-bin]# ./sbin/start-cli.sh -u
