環境

  • ONTAP 9
  • Microsoft LDAPサーバ
  • セキュアなLDAP
  • LDAPS
  • Start-TLSの実行

問題

  • ONTAP とMS LDAPサーバ間のLDAP接続を必要とする処理(たとえば、ADサイト検出)が失敗します。
  • ファイルのACLの変更(Windowsクライアント側のエラーメッセージ)
    cannot determine whether the computer is joined to a domain
  • でポート636のLDAPクライアントを有効にすると vserver services name-service ldap client modify 失敗します
  • LDAPサーバではユーザバインドパラメータを設定する必要があります [-bind-dn <ldap_dn>] - Bind DN (User)

  • EMSおよびSECDのログ Invalid credentialsには、セキュアLDAP接続を開始するときの障害に関連しているように見えます。

EMS

secd: secd.conn.auth.failure:notice]: Vserver (<vserver>) could not authenticate over the network to server (). Error: Invalid credentials (Service: LDAP (Active Directory), Operation: SiteDiscovery).
  • LDAPSまたはStart-TLSのどちらを使用するかによって、SECDログ内にそれ自体がわずかに異なる形で記録されます。
