Here is a quick sample of Power Shell snippet to list users from 3 different Active Directory groups:
1 2 3 | Import-Module ActiveDirectory $groups = "AWS-IAM-PCI-Prod-Admin","AWS-IAM-PCI-Prod-Deploy","AWS-IAM-PCI-Prod-Monitoring" foreach($group in $groups){Get-ADGroupMember -Identity $group -Recursive | Select-Object SamAccountName} |
It will list SamAccountName for all member users in those 3 Groups.
