System.Web.HttpException: 'Unable to connect to SQL Server database using User.IsInRole("string")

2

I have this code:

if (User.IsInRole("CanManageUsers"))
{
  return RedirectToAction("Index", "Account");
}

Which throws the following error:

System.Web.HttpException: 'Unable to connect to SQL Server database'

Now I can not figure out why because prior to that I'm successfully connecting to the same database and I fail to understand why in this particular case it fails. Is there someplace where you configure the database that the User class connects to?

I tried looking in the documentation but couldn't find anything on this issue.

Thanks in advance
