Mitigation checklist
- Set ldap_sudo_search_base explicitly in /etc/sssd/sssd.conf to restrict the search to the designated sudoers container: [domain/example.com] ldap_sudo_search_base = ou=sudoers,dc=example,dc=com Additionally, restrict LDAP ACLs to prevent non-admin principals from creating sudoRole objects outside the designated sudoers container.
