samba 4で構築したドメインにNetApp 9.5が登録できない


テスト環境作成のためNetAppシミュレータの9.5P6を作ってsamba 4で構築したActive Directory環境に登録しようとした・・・

netapp95sim::*> vserver cifs create -cifs-server netappcifs -domain ad.osakana.net -ou CN=Computers -vserver netappcifs -netbios-aliases netappcifs

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 "AD.OSAKANA.NET"
domain.

Enter the user name: administrator

Enter the password:

netapp95sim::*>

エラー発生。

なんか調べたところ、active-directoryというコマンドでも登録できるらしいのでそれでもテストしてみる。


netapp95sim::*> active-directory create -vserver netappcifs -account-name adserver -domain ad.osakana.net
  (vserver active-directory create)

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

Enter the user name: administrator

Enter the password:

netapp95sim::*>

同じようにエラー。

この後いろいろ試行錯誤した結果、自己証明CAをNetAppに入れればいいのでは?とやってみた。(「クラスタまたはSVMがクライアントであるSSLサーバを認証するためのサーバCA証明書のインストール」)

netapp95sim::*> security certificate install -vserver netappcifs -type server-ca

Please enter Certificate: Press <Enter> when done
-----BEGIN CERTIFICATE-----
<sambaの/usr/local/samba/private/tls/ca.pemの内容を張り付け>
-----END CERTIFICATE-----


Error: command failed: The certificate has expired.

netapp95sim::*>

ん?「The certificate has expired.」???

samba公式「Configuring LDAP over SSL (LDAPS) on a Samba AD DC」の「Verifying the certificate」に書いてある手法で確認してみます。

# ls -l  /usr/local/samba/private/tls

はい。証明書の有効期限切れでした。

手順がめんどいので、/usr/local/samba/private/tlsにあるファイルをリネームしてから「systemctl stop samba-ad-dc.service」「systemctl start samba-ad-dc.service」で強制再作成させました。
