Joining an SVM to an Active Directory using the ONTAP CLI Modify an Active Directory configuration using the ONTAP CLI Unjoin an Active Directory from your SVM using the NetApp ONTAP CLI

Updating SVM Active Directory configurations using the NetApp CLI

You can use the NetApp ONTAP CLI to join and unjoin your SVM to an Active Directory, and to modify an existing SVM Active Directory configuration.

Joining an SVM to an Active Directory using the ONTAP CLI

You can join existing SVMs to an Active Directory using the ONTAP CLI, as described in the following procedure. You can do this even if your SVM is already joined to an Active Directory.

To access the ONTAP CLI, establish an SSH session on the management port of the Amazon FSx for NetApp ONTAP file system or SVM by running the following command. Replace management_endpoint_ip with the IP address of the file system's management port.
```
[~]$ ssh fsxadmin@management_endpoint_ip
```
For more information, see Managing file systems with the ONTAP CLI.

Create a DNS entry for your Active Directory by providing the full directory DNS name (corp.example.com) and at least one DNS server IP address.


::>vserver services name-service dns create -vserver svm_name -domains corp.example.com -name-servers dns_ip_1, dns_ip_2

To verify the connection to your DNS servers, run the following command. Replace svm_name with your own information.


FsxId0ae30e5b7f1a50b6a::>vserver services name-service dns check -vserver svm_name

svm_name      172.31.25.207   up           Response time (msec): 1
2 entries were displayed.

To join your SVM to your Active Directory, run the following command. Note that you will must specify a computer_name that doesn't already exist in your Active Directory and provide the directory DNS name for -domain. For -OU, enter the OUs that you want the SVM to join, as well as the full DNS name in DC format.


::>vserver cifs create -vserver svm_name -cifs-server computer_name -domain corp.example.com -OU OU=Computers,OU=example,DC=corp,DC=example,DC=com

To verify the status of your Active Directory connection, run the following command:


::>vserver cifs check -vserver svm_name
                              
              Vserver : svm_name
                    Cifs NetBIOS Name : svm_netBIOS_name
                          Cifs Status : Running
                                 Site : Default-First-Site-Name

2 entries were displayed.

If you can't access shares after this join, determine whether the account you’re using to access the share has permissions. For example, if you're using the default Admin account (a delegated administrator) with an AWS managed Active Directory, you will must run the following command in ONTAP. The netbios_domain corresponds with your Active Directory’s domain name (for corp.example.com, the netbios_domain used here is example).
```
FsxId0123456789a::>vserver cifs users-and-groups local-group add-members -vserver svm_name -group-name BUILTIN\Administrators -member-names netbios_domain\admin
```

Modify an Active Directory configuration using the ONTAP CLI

You can use the ONTAP CLI to modify an existing Active Directory configuration. 

To access the ONTAP CLI, establish an SSH session on the management port of the Amazon FSx for NetApp ONTAP file system or SVM by running the following command. Replace management_endpoint_ip with the IP address of the file system's management port.
```
[~]$ ssh fsxadmin@management_endpoint_ip
```
For more information, see Managing file systems with the ONTAP CLI.

Run the following command to temporarily bring down the SVM's CIFS server: 


FsxId0123456789a::>vserver cifs modify -vserver svm_name -status-admin down

If you need to modify the DNS entries of your Active Directory, run the following command: 


::>vserver services name-service dns modify -vserver svm_name -domains corp.example.com -name-servers dns_ip_1,dns_ip_2

You can validate the connection status to your Active Directory's DNS servers using the vserver services name-service dns check -vserver svm_name command.


::>vserver services name-service dns check -vserver svm_name
                              Name Server
Vserver       Name Server     Status       Status Details
------------- --------------- ------------ --------------------------
svmciad       dns_ip_1        up           Response time (msec): 1
svmciad       dns_ip_2        up           Response time (msec): 1
2 entries were displayed.

If you need to modify the Active Directory configuration itself, you can change existing fields by using the following command, replacing:
- computer_name, if you want to modify the NetBIOS (machine account) name of the SVM.
- domain_name, if you want to modify the name of the domain. This should correspond with the DNS domain entry noted in Step 3 of this section (corp.example.com).
- organizational_unit, if you want to modify the OU (OU=Computers,OU=example,DC=corp,DC=example,DC=com).
You will need to reenter the Active Directory credentials that you used to join this device to the Active Directory.
```
::>vserver cifs modify -vserver svm_name -cifs-server computer_name -domain domain_name -OU organizational_unit
```
You can verify the connection status of your Active Directory connection using the vserver cifs check -vserver svm_name command.
When you finish modifying your Active Directory and DNS configuration, bring the CIFS server back up by running the following command:
```
::>vserver cifs modify -vserver svm_name -status-admin up
```

Unjoin an Active Directory from your SVM using the NetApp ONTAP CLI

The NetApp ONTAP CLI can also be used to unjoin your SVM from an Active Directory by following the steps below:

To access the ONTAP CLI, establish an SSH session on the management port of the Amazon FSx for NetApp ONTAP file system or SVM by running the following command. Replace management_endpoint_ip with the IP address of the file system's management port.
```
[~]$ ssh fsxadmin@management_endpoint_ip
```
For more information, see Managing file systems with the ONTAP CLI.
Delete the CIFS server that unjoined your device from the Active Directory by running the following command. For ONTAP to delete the machine account for your SVM, provide the credentials that you originally used to join the SVM to the Active Directory.  
```
FsxId0123456789a::>vserver cifs modify -vserver svm_name -status-admin down
```

If you need to modify the DNS entries of your Active Directory, run the following command: 


FsxId0123456789a::vserver cifs delete -vserver svm_name

In order to delete an Active Directory machine account for the CIFS server, you must supply the name and password of a Windows account with
sufficient privileges to remove computers from the "CORP.ADEXAMPLE.COM" domain. 

Enter the user name: user_name

Enter the password: 

Warning: There are one or more shares associated with this CIFS server
         Do you really want to delete this CIFS server and all its shares? {y|n}: y

Delete the DNS servers for your Active Directory by running the following command:


::vserver services name-service dns delete -vserver svm_name

If you see a warning like the following—indicating that dns should be removed as an ns-switch—and you don't plan to rejoin this device to an Active Directory, you can remove the ns-switch entries.


Warning: "DNS" is present as one of the sources in one or more ns-switch databases but no valid DNS configuration was found for Vserver
         "svm_name". Remove "DNS" from ns-switch using the "vserver services name-service ns-switch" command. Configuring "DNS" as a source
         in the ns-switch setting when there is no valid configuration can cause protocol access issues.

(Optional) Remove the ns-switch entries for dns by running the following command. Verify the source order, then remove the dns entry for the hosts database by modifying the sources so that they contain only the other sources listed. In this example, the only other source is files.


::>vserver services name-service ns-switch show -vserver svm_name -database hosts

                     Vserver: svm_name
Name Service Switch Database: hosts
   Name Service Source Order: files, dns


::>vserver services name-service ns-switch modify -vserver svm_name -database hosts -sources files

(Optional) Remove the dns entry by modifying the sources for the database host to include only files.
```
::>vserver services name-service ns-switch modify -vserver svm_name -database hosts -sources files
```
