how to add user programatically without interfering with cas module?

Question

I have created a module that bulk create user entities depending on ldap filters and assign selected roles . The problem is the connection with cas is then not working when a user entry has been already created

here is my code so far:

<?php /**
* @file
* Contains \Drupal\example\Form\ExampleForm.
*/

namespace Drupal\my_import_ldap\Form;

use Drupal\Core\Form\FormBase;
use Drupal\Core\Form\FormStateInterface;

/**
* Implements an example form.
*/
class MyImportLdapSettingsForm extends FormBase {

/**
* {@inheritdoc}
*/
public function getFormId() {

return 'my_ldap_import_settings_form';
}

/**
* {@inheritdoc}
*/
public function buildForm(array $form, FormStateInterface $form_state) {


    $system_roles = user_role_names(TRUE);


    $form['ldap_filter'] = array(
        '#type' => 'textarea',
        '#title' => $this->t('LDAP Filter'),
        '#description' => t('Specify LDAP filter used to populate Drupal user account'),
    );

    $form['actions2']['#type'] = 'actions';
    $form['actions2']['submit'] = array(
        '#type' => 'submit',
        '#value' => $this->t('Save Filter'),
        '#button_type' => 'primary',
    );

    $form['roles_list'] = array(
        '#type' => 'checkboxes',
        '#title' => $this->t('Rôles'),
        '#description' => t('Select the roles to assign created account'),
        '#options' => $system_roles,
    );


$form['actions']['#type'] = 'actions';

$form['actions']['submit'] = array(
'#type' => 'submit',
'#value' => $this->t('Import to Drupal People'),
'#button_type' => 'primary',

);
return $form;
}

/**
* {@inheritdoc}
*/
public function validateForm(array &$form, FormStateInterface $form_state) {

}

/**
* {@inheritdoc}
 *

 *
 *
 * add or update users, corresponding to the LDAP filters and add the selected roles
 *

public function submitForm(array &$form, FormStateInterface $form_state) {
    if ($_POST['op']== 'Import to Drupal People'){

        $filter = $form_state->getValue('ldap_filter');
        $roles =$form_state->getValue('roles_list');
        $selected_roles=array();
        foreach($roles as $key => $value)
        {
            if(is_string($value))
            {

            }
        }

}

Answer 1

my cas common name was wrong cause it is not the same as the ldap common name, here is the lines i have changed to make it work:

 $this->set_cas_user_name($account,$info[$i]["cn"][0],$info[$i]["uid"][0]);

 public function set_cas_user_name($account,$ldap_common_name,$cas_common_name){

 $cas_user_manager->setCasUsernameForAccount($account, $cas_common_name);
