Enables the user registration and login system.

Code

function user_authenticate($form_values = array()) {
  global $user;

  // Load the account to check if the e-mail is denied by an access rule.
  // Doing this check here saves us a user_load() in user_login_name_validate()
  // and introduces less code change for a security fix.
  $account = user_load(array('name' => $form_values['name'], 'pass' => trim($form_values['pass']), 'status' => 1));
  if ($account && drupal_is_denied('mail', $account->mail)) {
    form_set_error('name', t('The name %name is registered using a reserved e-mail address and therefore could not be logged in.', array('%name' => $account->name)));
  }

  // Name and pass keys are required.
  // The user is about to be logged in, so make sure no error was previously
  // encountered in the validation process.
  if (!form_get_errors() && !empty($form_values['name']) && !empty($form_values['pass']) && $account) {
    $user = $account;
    user_authenticate_finalize($form_values);
    return $user;
  }
  else {
    watchdog('user', 'Login attempt failed for %user.', array('%user' => $form_values['name']));
