Q: Some of the things we do in our logon scripts require the user to be a local administrator. How can the script tell if the user is a local administrator or not, using PowerShell 7. A: Easy using PowerShell 7 and the LocalAccounts module Local Users and GroupsThe simple answer is of course, easily. And since you ask, with PowerShell 7! But let’s begin lets begin by reviewing local users and groups in Windows. Every Windows system, except for Domain Controllers, maintains a set of local accounts – local users and local groups. Domain controllers use the AD and do not really have local accounts as such. You use these local accounts in addition to domain users and domain groups on domain-joined hosts when setting permissions. You can logon to a given server using a local account or a domain account. On Domain Controllers you can only login using a domain account. As with AD groups, local groups and local users each have a unique Security ID (SID). When you give a local user or group access to a file or folder, Windows adds that SID to the object’s Access Control List. This is the same way Windows enables you to give permissions to a local file or folder to any Active Directory user or group. Additionally, Windows and some Windows features create “well known” local groups. The intention is that you add users to these groups to enable those users to perform specific administrative functions on just those servers. Traditionally, you might have used the The Microsoft.PowerShell.LocalAccounts moduleIn PowerShell 7 for Windows, you can use the This module contains 15 cmdlets, which you can view like this:
As you can tell, these cmdlets allow you to add, remove, change, enable and disable a local user or local group And they allow you to add, remove and get the local group’s members. These cmdlets are broadly similar to the ActiveDirectory cmdlets, but work on local users. And as noted above, you can use domain users/groups as a member of a local group should you wish or need to. You use the
As you can see in this output, the local Administrators group on this host contains domain users and groups as well as local users Is the User an Administrator?It’s easy to get membership of any local group, as you saw above. But what if you want to find out if a given user is a member of some local administrative group? That too is pretty easy and take a couple of steps. One way you can get the name of the current user is by using
If the administrative group contains user running the script, then In this snippet, we just echo the fact that the user is, ir is not, a member of the local administrators group. You can adapt it to ensure a user is a member of the appropriate group before attempting to run certain commands. And you can also adapt it to check for membership in other local groups such as Backup Operators or Hyper-V Users which may be relevant. In your logon script, once you know that the user is a member of a local administrative group, you can carry out any tasks that require that membership. And if the user is not a member of the group, you could echo that fact, and avoid using the relevant cmdlets. SummaryUsing the Local Accounts module in PowerShell 7, it’s easy to manage local groups! You can, of course, manage the groups the same way in Windows PowerShell. Tip of the HatThis article was originally a VBS based solution as described in an earlier blog post. I am not sure who the author of the original post was – but thanks. The post Is a User A Local Administrator? appeared first on PowerShell Community. Which of the following cmdlets would you use to create a local user account?Description. The New-LocalUser cmdlet creates a local user account. This cmdlet creates a local user account or a local user account that is connected to a Microsoft account.
Which cmdlet is used to add a new member to a group?The Add-ADGroupMember cmdlet adds one or more users, groups, service accounts, or computers as new members of an Active Directory group. The Identity parameter specifies the Active Directory group that receives the new members.
What is the cmdlet to create a new user in the directory?The New-ADUser cmdlet creates an Active Directory user. You can set commonly used user property values by using the cmdlet parameters.
Which PowerShell cmdlet is used to add a new user to the account?Create New User Accounts using the New-ADUser Cmdlet.
