古いONTAPがActive Directoryに参加できない


古いONTAP、具体的にはONTAP 8.3.2環境の移行案件があったので、検証のためにONTAP simulatorのONTAP 8.3.2版を仮想環境上に作成して、Active Directoryに参加しようとしたところ下記のエラーとなった。(なお、接続先Active Direcrotyはsamba 4.14.5で構成している)

ontap832::> vserver cifs create -cifs-server share226 -domain adosakana.local -vserver share226

In order to create an Active Directory machine account for the CIFS server, you
must supply the name and password of a Windows account with sufficient
privileges to add computers to the "CN=Computers" container within the
ADOSAKANA.LOCAL domain.

Enter the user name: administrator

Enter the password:

これは暗号化の問題なので「vserver cifs security show」で設定項目を確認する。

ontap832::> vserver cifs security show -vserver share226

Vserver: share226

ONTAP 8.3.2無印では関連するオプション「SMB2 Enabled for DC Connections」を設定する項目が無い

ontap832::> version -node *

ontap832-01:
NetApp Release 8.3.2: Tue Feb 23 23:35:06 UTC 2016

アップデータを探したところ、832P12_q_image.tgz があったので、「ONTAP 9.7シミュレータをアップデートする手法」と同じ手法でアップデートを行った。

ontap832::> version -node *

ontap832-01:
NetApp Release 8.3.2P12: Mon Aug 14 02:57:01 UTC 2017

ONTAP 8.3.2P12であれば、「SMB2 Enabled for DC Connections」が存在していた。

ontap832::> vserver cifs security show -vserver share226

Vserver: share226

        SMB2 Enabled for DC Connections:                   -

設定を変更

ontap832::> vserver cifs security modify -vserver share226 -smb1-enabled-for-dc-connections false -smb2-enabled-for-dc-connections true

ontap832::> vserver cifs security show -vserver share226

Vserver: share226

        SMB2 Enabled for DC Connections:                true

そして、Active Directoryへの参加

ontap832::> vserver cifs create -cifs-server share226 -domain adosakana.local -vserver share226

In order to create an Active Directory machine account for the CIFS server, you
must supply the name and password of a Windows account with sufficient
privileges to add computers to the "CN=Computers" container within the
ADOSAKANA.LOCAL domain.

Enter the user name: administrator

Enter the password:

Warning: An account by this name already exists in Active Directory at
         CN=SHARE226,CN=Computers,DC=adosakana,DC=local
         Ok to reuse this account? {y|n}: y

今度は成功した。
