![the properties of the windows login](https://i.stack.imgur.com/torSC.png)

In this picture, you can see if I login using windows authentication, the default user and schema are dbo.

I have a database called trunk2 and its default user is trunk2 and default schema is trunk2.

If I login as "trunk2", I can access the schema a"trunk2" as the default schema

But if I login using the windows authentication, I am not able to populate the schema "trunk2" as the default schema for the database trunk2

It is populating the schema "dbo" as the default schema. Why ? 

How can I login using the Windows login and access the schema "trunk2" as the default schema of the database "trunk2"?

Please see in the below picture, for the login "trunk2", I have no problem in accessing the default schema "trunk2" for database "trunk2" and default user "trunk2"
