+    Configuring a bind DN in an LDAP or Active Directory (AD) realm without
+    a corresponding bind password will prevent node from starting
+  area: Cluster and node setting
+  details: -|
+    For LDAP or AD authentication realms, setting a bind DN (via the
+    `xpack.security.authc.realms.ldap.*.bind_dn` or `xpack.security.authc.realms.active_directory.*.bind_dn`
+    realm settings) without a bind password is a misconfiguration that may prevent successful authentication
+    to the node. Nodes will fail to start if a bind DN is specified without a password.
+  impact: -|
+    If you have a bind DN configured for an LDAP or AD authentication
+    realm, set a bind password for {ref}/ldap-realm.html#ldap-realm-configuration[LDAP]
+    or {ref}/active-directory-realm.html#ad-realm-configuration[Active Directory].
+    Configuring a bind DN without a password prevents the misconfigured node from starting.
