ONTAP API が失敗しました： Failed to create the Active Directory machine account "ファイルサーバ名". Reason: LDAP Error: Strong authentication is required Details: Error: Machine account creation procedure failed [ 136] Loaded the preliminary configuration.

調べたところ、sambaのglobal設定で「ldap server require strong auth = no」を設定する、とのこと。
これを設定し、sambaを再起動したところ、参加できた。
ONTAP 9.7にて、上記手順を実施した上で参加を試みたところ「Unable to connect to NetLogon service on」というエラーになった。

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名" domain.
Enter the user name: administrator
Enter the password:
Warning: An account by this name already exists in Active Directory at
CN=ファイルサーバ名,CN=Computers,DC=xx,DC=xx.
If there is an existing DNS entry for the name ファイルサーバ名, it must be
removed. Data ONTAP cannot remove such an entry.
Use an external tool to remove it after this command completes.
Ok to reuse this account? {y|n}: y
