Question

I am creating a website  but in the database I use windows authentication   I know that you use this for SQL authentication   lt connectionStrings gt        lt add name  NorthwindContex          connectionString  data source localhost         initial catalog northwind persist security info True          user id sa password P ssw0rd          providerName  System Data SqlClient    gt    lt  connectionStrings gt    How do I modify this to work with windows authentication

For connecting to a sql server database via Windows authentication basically needs which server you want to connect , what is your database name , Integrated Security info and provider name.

Basically this works:

<connectionStrings>      
<add name="MyConnectionString"
         connectionString="data source=ServerName;
   Initial Catalog=DatabaseName;Integrated Security=True;"
         providerName="System.Data.SqlClient" />
</connectionStrings>

Setting Integrated Security field true means basically you want to reach database via Windows authentication, if you set this field false Windows authentication will not work.

It is also working different according which provider you are using.

SqlClient both Integrated Security=true; or IntegratedSecurity=SSPI; is working.
OleDb it is Integrated Security=SSPI;
Odbc it is Trusted_Connection=yes;
OracleClient it is Integrated Security=yes;

Integrated Security=true throws an exception when used with the OleDb provider.

Replace the username and password with Integrated Security SSPI   So the connection string should be    lt connectionStrings gt    lt add name  NorthwindContex      connectionString  data source localhost     initial catalog northwind persist security info True      Integrated Security SSPI       providerName  System Data SqlClient    gt    lt  connectionStrings gt
