  Active Directory: Verify if a user exists (???)

  Feb 17, 2009 06:04 PM|LINK

  Hi friends, I'm developing a system to manage the users of a domain. Functions to create and update are already been createds, but is missing a function to verify if a user exists in Active Directory. I have tried to use the code typed below:

  public static bool UserExists(string user) {

  bool exist = false;

  if (DirectoryEntry.Exists("WinNT://casa.local/10.1.1.37/" + user)) exist = true;

  return exist; }

  When the user exists, the function DirectoryEntry.Exists returns true and the method continue to end. But, if the user not exists, the function DirectoryEntry.Exists not returns false, but throw a Exception "Generic error". I already tried to use the DirectorySearcher objects, but return error that the server not support search.

  I need a solution to my problem, a method to verify if a user exist.

  If you can help me, I"ll be happy =)

  Thank You!
