We can now see that the account was created with the appropriate values that we specified during creation and is no longer using the default values as with the first account. Create Active Directory Security Group 2. Group managed service accounts require a key distribution service (KDS) using the AD PowerShell module. These accounts can be used simultaneously on several servers, so that all service instances used the same account, like in Load Balancer (NLB), cluster services, etc. This topic for the IT professional introduces the group Managed Service Account by describing practical applications, changes in Microsoft's implementation, and hardware and software requirements. You also cannot create a root key in a child domain. Managed Service Accounts (MSAs) and Group Managed Service Accounts (gMSAs), on the other hand, are domain accounts already, so when they access the network resources, they do so using the domain account … This document describes how to get started with them. In the below example I used Windows PowerShell to view the root key in my child domain and the output did not display the root key. This can also be updated later or you can specify the SamAccountName value that you want to use when creating the account. By providing a gMSA solution, services can be configured for the new gMSA principal and the password management is handled by Windows.Using a gMSA, services or service administrators do not need to manage password synchronization between service instances. What are group managed service accounts? There are no configuration steps necessary to implement MSA and gMSA using Server Manager or the Install-WindowsFeature cmdlet. Since this is a well-documented process, we won't go into the specific steps here. It uses an Add-KdsRootkey PowerShell cmdlet. Beginning with Windows Server 2008 R2, DES is disabled by default. But now that we have Group Managed Service Accounts (gMSAs), there are many more places they can be used. Enter Group Managed Service Accounts. Another common finding is that accounts were created long ago and current support staff are not sure on which systems the account are used. For more information about supported encryption types, see Changes in Kerberos Authentication. MSA (Managed Service Accounts) have been around since Windows Server 2008R2 with the latest incarceration of features being introduced with Windows 2012R2. Managed Service Accounts Documentation for Windows 7 and Windows Server 2008 R2, Managed Service Accounts in Active Directory, Getting Started with Group Managed Service Accounts, Managed Service Accounts in Active Directory Domain Services, Managed Service Accounts: Understanding, Implementing, Best Practices, and Troubleshooting, Active Directory Domain Services Overview. Initial setup steps - done only once for each domain 1.1. A standalone Managed Service Account (sMSA) is a managed domain account that provides automatic password management, simplified service principal name (SPN) management and the ability to delegate the management to other administrators. The command I use is as follows: Get-ADServiceAccount gmsa-test01 -Properties * | FL DNSHostName,KerberosEncryptionType,ManagedPasswordIntervalInDays,Name,PrincipalsAllowedToRetrieveManagedPassword,SamAccountName. Member hosts can obtain the current and preceding password values by contacting a domain controller. This is first introduced with windows server 2012. When used in an Active Directory environment that runs the Windows Server 2008 R2 Domain Functional Level (DFL), or up, and using the Active Directory Domain Services Remote Server Administration Tools (AD DS RSAT) on at least Windows Server 2012 or Windows 8, gMSAs offer thes… I have however successfully deployed Azure ATP in my 2 domain forest. The Microsoft Key Distribution Service (kdssvc.dll) provides the mechanism to securely obtain the latest key or a specific key with a key identifier for an Active Directory account. The DC uses the account's msDS-SupportedEncryptionTypes attribute to determine what encryption the server supports and, if there is no attribute, it assumes the client computer does not support stronger encryption types. To eliminate this drawback, Microsoft added the feature of Group Managed Service Accounts (gMSA) to Windows Server 2012. The attributes have been updated successfully except that the PrincipalsAllowedToRetrieveManagedPassword value now only contains a single server. Using a gMSA, services or service administrators do not need to manage password synchronization between service instances. The previous value which contained two servers was replaced so now instead of having 3 servers in the list, we end up with the 1 server that we specified with the Set-ADServiceAccount command. The technology of Managed Service Accounts (MSA) was firstly introduced in Windows Server 2008 R2 to automatically manage (change) passwords of service accounts.Using Managed Service Accounts, you can considerably reduce the risk of system accounts running system services being compromised. They can now be used for SQL Server and they’re a lot more flexible and easier to work with. You may want to specify the account to use only the highest level of encryption. This means you can deploy a server farm that supports a single identity to which existing client computers can authenticate without knowing the instance of the service to which they are connecting.
