Check if user exists in Active Directory
- by K.R.
Hello,
I need to check if an user exists in AD and if so, retrieve some user information. I have been able to do this as shown below. But, it is very slow. Is there any way to do this faster?
Thanks!
using System;
using System.DirectoryServices;
using System.DirectoryServices.AccountManagement;
namespace ConsoleApplication1
{
class Program
{
static void Main()
{
Console.WriteLine("Enter AD account name...");
string strADLoginName = Console.ReadLine();
using(PrincipalContext context = new PrincipalContext(ContextType.Domain,"DEVMC"))
{
using (UserPrincipal user = UserPrincipal.FindByIdentity(context, strADLoginName))
{
bool userExists = (user != null);
if (userExists)
{
Console.WriteLine("User exists");
Console.WriteLine(user.EmailAddress);
}
else
{
Console.WriteLine("User doesn't exist");
}
}
}
Console.ReadKey();
}
}
}
