Learn about\n[these open source connectivity tools](/managed-microsoft-ad/docs/connect-to-active-directory-domain#connecting_to_a_domain-joined_linux_vm).\n\nBefore you begin\n----------------\n\n- [Create a Managed Microsoft AD domain](/managed-microsoft-ad/docs/quickstart-create-domain).\n\n- [Create a Linux VM](/compute/docs/create-linux-vm-instance#create_a_virtual_machine_instance).\n When you create the VM, make sure that you complete the following tasks:\n\n - On the **Public images** tab, select the appropriate distribution. For example, **Ubuntu 22.04 LTS** or **Red Hat Enterprise Linux 8**.\n - Select a [Linux version that Managed Microsoft AD\n supports](/managed-microsoft-ad/docs/os-versions#linux-domain-join).\n - Create the VM in the project that hosts your Managed Microsoft AD domain. If your Managed Microsoft AD domain has a [Shared VPC](/vpc/docs/shared-vpc) as an authorized network, you can also create the VM in any of the Shared VPC service projects.\n - Create the VM on a VPC network that you have peered with the Managed Microsoft AD domain.\n- Install `realmd` on the VM. Learn about\n [`realm`](https://www.systutorials.com/docs/linux/man/8-realm/).\n\n See\n [Ubuntu](https://ubuntu.com/server/docs/service-sssd-ad#software-installation-3)\n and [Red\n Hat](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/windows_integration_guide/realmd-prepreqs)\n documentation for instructions.\n\n The following are some sample commands: \n\n ### Ubuntu 22.04 LTS or later\n\n ```\n apt-get update\n apt-get install realmd sssd packagekit\n ```\n\n ### RHEL 8 or later\n\n ```\n sudo yum install realmd oddjob oddjob-mkhomedir\n sssd adcli\n ```\n\nJoin a Linux VM to a domain\n---------------------------\n\nTo join a Linux VM to a domain, you need the following information:\n\n- The domain name of your Managed Microsoft AD domain. For example,\n `mydomain.example.com`.\n\n- The username and password of an account that has permissions to join a VM to\n the domain. By default, members of the `Cloud Service Domain Join Accounts`\n group have these permissions. For more information about the default groups\n that Managed Microsoft AD creates, see\n [Groups](/managed-microsoft-ad/docs/objects#groups).\n\n - The username must be in the following format: \u003cvar translate=\"no\"\u003eUSERNAME\u003c/var\u003e@\u003cvar translate=\"no\"\u003eDOMAIN_NAME\u003c/var\u003e. The domain name part of the username must be in uppercase. For example, `user@MYDOMAIN.EXAMPLE.COM`.\n\nYou can join the Linux VM to the Managed Microsoft AD domain using the\n[`realm\njoin`](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/windows_integration_guide/realmd-domain#realm-join)\ncommand. The following is a sample command: \n\n```\nrealm join DOMAIN_NAME -U 'USERNAME@DOMAIN_NAME'\n```\n\nFor verbose output, add the `-v` flag at the end of the command.\n\n### Specify account location with `realm join`\n\nBy default, the `realm join` command creates a machine account that is located at: \n\n```\nCN=ACCOUNT_NAME,OU=Computers,OU=Cloud,DC=MACHINE,DC=MID_LEVEL,DC=EXTENSION\n```\n\nTo specify where to create the account, use the `--computer-ou` flag to provide\nthe path for the `realm join` command. The following example shows how to\nspecify the path: \n\n```\n--computer-ou=\"OU=CUSTOM_OU,DC=MACHINE,DC=MID_LEVEL,DC=EXTENSION\"\n```\n\nThe user must have the permissions that are required to create accounts in the specified OU.\n\nRemove a Linux VM from a domain\n-------------------------------\n\nTo remove a Linux VM from a domain, you need the domain name of your\nManaged Microsoft AD domain and the username of your user account.\n\nYou can remove a Linux VM from the Managed Microsoft AD domain using the\n[`realm\nleave`](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/windows_integration_guide/realmd-ad-unenroll)\ncommand. The following is a sample command: \n\n```\nrealm leave DOMAIN_NAME -U 'USERNAME@DOMAIN_NAME'\n```\n\nWhat's next\n-----------\n\n- [Connect to a Managed Microsoft AD domain](/managed-microsoft-ad/docs/connect-to-active-directory-domain).\n- Learn about the [delegated administrator account](/managed-microsoft-ad/docs/how-to-use-delegated-admin)."]]
