#33631 closed enhancement (fixed)

Add filter to prevent user creation during site creation

Reported by: mackensen's profile mackensen Owned by: rachelbaker's profile rachelbaker
Milestone: 4.5 Priority: normal
Severity: normal Version: 4.4
Component: Networks and Sites Keywords: has-patch commit
Focuses: multisite Cc:


We administer a multisite environment with external (LDAP) authentication configured. We do not allow local accounts. Our procedure when creating a new site is to add the soon-to-be-administrator from external authentication to the top-level site (if they did not already exist) before creating the site. If someone misses that first step, we wind up with an unwanted local account which then has to be fixed. What would be cool is a filter/hook in wp-admin/network/site-new.php that attaches to email_exists and lets you stop the site creation process if the user doesn't exist.

  • Component changed from Administration to Networks and Sites

A workaround:

function wp33631_check_for_existing_user_during_site_creation() {
	if ( ! isset( $_REQUEST['action'] ) || 'add-site' !== $_REQUEST['action'] ) {

	if ( ! email_exists( $_POST['blog']['email'] ) ) {
		wp_die( 'User does not exist.' );
add_action( 'admin_init', 'wp33631_check_for_existing_user_during_site_creation' );

Working on this at WCUS Contributor Day. I've added a new action network_site_new_created_user_pending which fires immediately before user creation, so you could hook into it with a simple wp_die or whatever else you might want to do. I could see external auth attempting to auto provision the account.

@mackensen Looks like you have wrong parameter type in the inline docs for the filter. Can you check it?

New network_site_new_created_user_pending action fires before a new user will be created via the network site-new.php page.

  • Milestone changed from Awaiting Review to 4.5
  • Resolution fixed deleted
  • Status changed from closed to reopened

We can probably tighten up the naming on this a bit to be more clear. Nothing is pending yet, as we still need to go through some other user checks to see if the email is valid before continuing. Using pre_ seems to make sense. I've added 33631.2.diff with this change.
