I linked the users table of GeoNetwork 3.10.2 with my application database so everytime I create/update a user in the app is also created/updated in geonetwork, now I want that once I log in the app, I also automatically be logged into GeoNetwork.
I found this thread about using JSESSION : https://gis.stackexchange.com/questions/231775/accessing-geonetwork-api-by-jsessionid-cookie 
but I got no success response 

```
const httpHeaders = { headers: new HttpHeaders()
      .set('Content-Type', 'application/x-www-form-urlencoded')
    }
    
let body = {"username": "userLogin","password": "userPass" };
this.http.post<any>('http://localhost:8080/geonetwork/srv/eng/catalog.signin', body , httpHeaders)
      .pipe(map(( res: Response ) => JSON.parse(JSON.stringify(res)) )).subscribe( response => {
      console.log('response   :   ' ,response);      
});
```

from the file log I got : 
```
0:0:0:0:0:0:0:1 - - [31/Dec/2020:03:43:34 -0800] "POST /geonetwork/srv/eng/catalog.signin HTTP/1.1" 403 1114
```
