# membership_of_AWS_IAM_Groups.ps1
<#
Description: This will show the membership of IAM Users in a list of AWS IAM Groups.
For Password_LastUsed, if the account does not have a password, which means no access to AWS Console, or if the password was never used, it outputs "1/1/0001 12:00:00 AM", I capture this and replace with a blank.
