Connect to DataBase programmatically with Integrated Security in SharePoint - which account credentials are used?

Question

Hi to All!
I have a simple question. I connect to DataBase programmatically, using SqlConnection and Integrated Security in connection string. It works! But I cannot understand -  which account credentials are used? My Windows account(under which I was logged
in) or NetworkService Account, or something else?
If I was logged in as FBA user in SharePoint - what in this case?

Hi MaryBath,
When you use integrated security = true it means the same as integrated security = SSPI and in this case the current Windows account credentials are used for authentication and if you set the integrated
security = false you have to provide UserName and Password . so for your question it uses the current windows account credentials.
here is the Microsoft link for the same...

If your code is executing on server in SharePoint (in webparts or features or application page). it will take the windows account of the server to connect to the database because all are executing on server not on client machine. your
login credentials has nothing to do with it.
Note: there are 2 authentication Windows Authentication and SQL Authentication so make sure that on database windows authentication is enabled (it will only work when windows authentication is enabled....
