connectionstring, connnection properties and localdb

connectionstring, connnection properties and localdb

Hello,
have
con.ConnectString:='Provider=SQLNCLI11.1;Integrated Security=SSPI;Initial Catalog=somedatabase;Data Source=(localdb)\mssqllocaldb';
this works correctly.
When i want to set this values as properties of object con (TMSConnection), i did not find corresponding property of value Integrated Security=SSPI, which is important for using localdb. How can i set thist without using connecstrstring?

Second question, Can i use anyhow direct mode (prdirect option, or TDS value in constr) with localdb ?
Thanks.
Robert.
