When I try to connect do MSSQL server using windows authentification(mssql.secure_connection=on) I cannt connect to the server with client user account. It uses servers anonymous account({servername}\IUSR_{servername}). Even when I try to use normal connection(mssql_connect({servername},{usr},{psw})) it switches to this user. Only when I switched the mssql.secure_connection to off it worked, but naturally only non-autherized connection. Any Idea?
