Werk #22140 stopped you from deleting a customer that groups, users or LDAP/SAML connections were still assigned to. Several other objects can be assigned to a customer too, and Checkmk ignored them:

  • Passwords (Setup > General > Passwords)
  • BI aggregations
  • Event Console rule packs and rules

After you deleted the customer, these objects were left pointing to a customer that no longer existed.

Checkmk now refuses to delete a customer while any of these objects are still assigned to it. As with the objects from werk #22140, the page Setup > Users > Customers lists them with a link to their edit page, and the REST API endpoint for deleting a customer returns status 409 and names them.
