First Steps Automating AD

by Jul 7, 2015

When you download the free RSAT tools from Microsoft, these include the ActiveDirectory module. It contains a rich set of cmdlets to manage Active Directory accounts.

Provided you are connected to an Active Directory, you can use the following samples to get familiar with these new cmdlets:

# find your own user account by SAMAccountName
Get-ADUser -Identity $env:USERNAME

# find user account by DN
Get-ADUser -Identity 'CN=TWeltner,OU=Users,OU=Hannover,OU=Trainees,DC=powershell,DC=local'

# find your own user account and return all available attributes
Get-ADUser -Identity $env:USERNAME -Properties * 

# find your own user account and change attributes
Get-ADUser -Identity $env:USERNAME | Set-ADUser -Description 'My account'

# find all user accounts where the SAMAccount name starts with "T"
Get-ADUser -Filter 'SAMAccountName -like "T*"'

# find user account "ThomasP" and use different logon details for AD

# logon details for your AD
$cred = Get-Credential
$IPDC = ''
Get-ADUser -Identity ThomasP -Credential $cred -Server $IPDC

# find all groups and output results to gridview
Get-ADGroup -Filter * | Out-GridView

# find all groups below a given search root
Get-ADGroup -Filter * -SearchBase 'OU=test,DC=powershell,DC=local'

# get all members of a group
Get-ADGroupMember -Identity 'Domain Admins' 

# create new user account named "Tom"
# define password
$secret = 'Initial$$00' | ConvertTo-SecureString -AsPlainText -Force
$secret = Read-Host -Prompt 'Password' -AsSecureString
New-ADUser -Name Tom -SamAccountName Tom -ChangePasswordAtLogon $true -AccountPassword $secret -Enabled $true 

# delete user account "Tom"
Remove-ADUser -Identity Tom -Confirm:$false

# create an organizational unit named "NewOU1" in powershell.local
New-ADOrganizationalUnit -Name 'NewOU1' -Path 'DC=powershell,DC=local'

# all user accounts not used within last 180 days
$FileTime = (Get-Date).AddDays(-180).ToFileTime()
$ageLimit = "(lastLogontimestamp<=$FileTime)"
Get-ADUser -LDAPFilter $ageLimit
