Combined with `SearchControls.setCountLimit(1)` on the same call site, this allows three distinct attack primitives:\n\n1. **Authentication confusion** — typing username `*` causes the realm to construct filter `cn=*`, return the first directory entry (typically a privileged account in AD ordering), and attempt bind against that DN with the attacker's password.\n2. **Audit log evasion** — payload `bob)(uid=alice` is recorded verbatim in audit logs while the realm searches with the malformed filter, breaking accountability/compliance (SOX, PCI-DSS, ISO 27001).\n3. **Directory enumeration** — wildcards and timing differences allow reconnaissance of OU structure and admin group membership.\n\nA repo-wide search for any LDAP escape helper (`escapeLdap`, `encodeFilter`, `escapeFilter`, `ldapEscape`) returns **zero hits** — the defense is not just missing, it was never added.\n\n> **Applicability note:** This realm is opt-in.
