I love HeidiSQL ! Long time I was working with MySQL Workbench but 3 days ago I heard about HeidiSQL and I will no longer use any ohter

When connecting to a MSSQL Server with UserName & PWD it works, using SQL Server Authentification.
I at the moment have no idea how to connect to this 2005 MSSQL using integrated Windows Security ?
What do I have to do or is this feature currently not available.
Cheers
Robert
