Login Failed issue with SSIS

  • Hi Team,

    When I run my SSIS package directly using command utility,there are no issues.

    When I execute same package via .net c# code, I get login failed for 'xxxx'.

    SSIS package uses dtsconfig and there is ann element for connectionstring which is like below:

    "data source=localhost;User ID=sa;Password=test123;Provider=SQLNCLI10";

    Though, when I set it to "Integrated Security=SSPI;" it executes successfuly via c#.

    I have to use SQL user id as this is the only login with dbcreator role.

    Any pointers would be helpful.

  • Sorry if this is an obvious question, but has the SQL instance been set to mixed mode authentication?

  • Yes, no problems with SQL instance

    Did you get this working? My next suggestion would be to attempt to capture the exact command line which is being sent by the C# program and see whether that gives you any pointers.

  • I am using Integrated Security = SSPI now, unable to resolve this error.

    That's the better solution anyway.
