unable to add roles in asp.net identity

I was using the following code to add roles of the user. 

    Roles.AddUserToRole(model.Email, "COMPANYVIP");

and then i got this error:

    The Role Manager feature has not been enabled

after some research i found out that we have to add the following connection string in web.config

    <configuration>
      <system.web>
        <roleManager enabled="true" />
      </system.web>
    </configuration>

adding this eliminated my first error but now i get this error:

    A network-related or instance-specific error occurred while establishing a connection to SQL Server

what should i do now?

Remove your change in web.config and in Startup.Auth add the following reference to ConfigureAuth:

public void ConfigureAuth(IAppBuilder app)
{
    app.CreatePerOwinContext(ApplicationDbContext.Create);
    // Add this reference to RoleManager (without changing any other items)
    // Make sure it is added below ApplicationDbContext.Create
    app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);
}

Then in your Controller, make sure it includes this in the constructor:

public class YourController : Controller
{
    // Add this
    private ApplicationRoleManager _roleManager;

    // Add roleManager
    public YourController(ApplicationRoleManager roleManager)
    {
        // Add this
        RoleManager = roleManager;
    }

    public ApplicationRoleManager RoleManager {
        get {
            return _roleManager ?? HttpContext.GetOwinContext().Get<ApplicationRoleManager>();
        }
        private set {
            _roleManager = value;
        }
    }
}

and also include this in the Controller's Dispose (if you have it):

protected override void Dispose(bool disposing)
{
    if (disposing)
    {
        // include this
        if (_roleManager != null)
        {
            _roleManager.Dispose();
            _roleManager = null;
        }
    }

    base.Dispose(disposing);
}

You may also need to add this code to IdentityConfig (in the App_Start folder if you're using the template):

public class ApplicationRoleManager : RoleManager<IdentityRole>
{
    public ApplicationRoleManager(IRoleStore<IdentityRole, string> roleStore)
    : base(roleStore)
    { }

    public static ApplicationRoleManager Create(
        IdentityFactoryOptions<ApplicationRoleManager> options,
        IOwinContext context)
    {
        var manager = new ApplicationRoleManager(
            new RoleStore<IdentityRole>(context.Get<ApplicationDbContext>()));
        return manager;
    }
}

You should now be able to use the RoleManager in the Controller.
