You can't join a Storage Virtual Machine (SVM) to Active Directory - FSx for ONTAP

You can't join a Storage Virtual Machine (SVM) to Active Directory

If you're unable to join your Storage Virtual Machines (SVM) to your Active Directory (AD), first review Using Amazon FSx SVMs with an Active Directory. Common problems preventing a successful SVM join to your AD are listed below.

Amazon FSx can't reach self-managed AD DNS server or domain controllers

Creating an SVM joined to your self-managed Active Directory fails with the following error message:

Amazon FSx is unable to communicate with your Active Directory domain controller(s). Please delete your storage virtual machine and create a new one once you've allowed network traffic between Amazon FSx and your domain controller(s) as recommended in the Amazon FSx user guide.

Use the following steps to troubleshoot and resolve this issue:

  1. Verify that you followed the prerequisites for having network connectivity and routing established between the subnet(s) where your file system resides, and your self-managed Active Directory. For more information, see Prerequisites for using a self-managed Microsoft AD.

  2. Verify that you configured the VPC security groups that you associated with your Amazon FSx file system, along with any VPC network ACLs, to allow outbound network traffic on all ports.

    Note

    If you want to implement least privilege, you can allow outbound traffic only to the specific ports required for communication with the Active Directory domain controllers. For more information, see the Microsoft Active Directory documentation.

  3. Verify that your Active Directory domain's DNS servers and domain controllers are active and able to respond to requests for the domain provided.

  4. Make sure that the firewall rules on your Active Directory domain's domain controllers allow traffic from your Amazon FSx file system. For more information, see the Microsoft Active Directory documentation.

Amazon FSx can't connect to AD domain controllers due to invalid service account credentials

Creating an SVM joined to your self-managed Active Directory fails with the following error message:

Amazon FSx is unable to establish a connection with your Active Directory domain controller(s) because the service account credentials provided are invalid. To fix this problem, delete your storage virtual machine and create a new one using a valid service account as recommended in the Amazon FSx user guide.

Use the following steps to troubleshoot and resolve this issue:

  1. Verify that you're entering only the user name as input for the Service account username, such as ServiceAcct, in the self-managed Active Directory configuration.

    Important

    Do not include a domain prefix (corp.com\ServiceAcct) or domain suffix (ServiceAcct@corp.com) when entering the service account user name. Do not use the distinguished name (DN) when entering the service account user name (CN=ServiceAcct,OU=example,DC=corp,DC=com).

  2. Verify that the service account that you provided exists in your Active Directory domain.

  3. Make sure that you delegated the required permissions to the service account that you provided. The service account must be able to create and delete computer objects in the OU in the domain to which you're joining the file system. The service account also needs, at a minimum, to have permissions to do the following:

    • Reset passwords

    • Restrict accounts from reading and writing data

    • Validated ability to write to the DNS hostname

    • Validated ability to write to the service principal name

    For more information about creating a service account with correct permissions, see Delegating privileges to your Amazon FSx service accountwarning.

Amazon FSx can't connect to AD domain controllers due to insufficient service account credentials

Creating an SVM joined to your self-managed Active Directory fails with the following error message:

Amazon FSx is unable to establish a connection with your Active Directory domain controller(s). This is due to either the port requirements for the Active Directory have not been met, or the service account provided does not have permission to join the storage virtual machine to the domain with the specified organizational unit. To fix this problem, delete your storage virtual machine and create a new one referring to configuration requirements specified in the Amazon FSx user guide.

To resolve this issue, make sure that you delegated the required permissions to the service account that you provided. The service account must be able to create and delete computer objects in the OU in the domain to which you're joining the file system. The service account also needs, at a minimum, to have permissions to do the following:

  • Reset passwords

  • Restrict accounts from reading and writing data

  • Validated ability to write to the DNS hostname

  • Validated ability to write to the service principal name

For more information about creating a service account with correct permissions, see Delegating privileges to your Amazon FSx service accountwarning.

Amazon FSx can't connect to the AD domain controllers because the organizational unit specified doesn't exist or isn't accessible

Creating an SVM joined to your self-managed Active Directory fails with the following error message:

Amazon FSx is unable to establish a connection with your Active Directory domain controller(s). This is because the organizational unit you specified either doesn't exist or isn't accessible to the service account provided. To fix this problem, delete your storage virtual machine and create a new one specifying an organizational unit to which the service account can join the storage virtual machine as recommended in the Amazon FSx user guide.

Use the following steps to troubleshoot and resolve the issue:

  1. Verify that the OU you provided is in the Active Directory Domain.

  2. Make sure that you delegated the required permissions to the service account that you provided. The service account must be able to create and delete computer objects in the OU in the domain to which you're joining the file system. The service account also needs, at a minimum, to have permissions to do the following in the OU you provided:

    • Reset passwords

    • Restrict accounts from reading and writing data

    • Validated ability to write to the DNS hostname

    • Validated ability to write to the service principal name
