While fessing tests in my lab, I got tired of creating users User01 groups, etc ... So I decided to create a script Powershell to create a similar structure to that of a company, allowing me to automatically create OUs, users, groups, computers, from a CSV file.
This powershell function creates the Active Directory infrastructure of a fake enterprise by creating OUs, groups, users, computers.
- Users : 75
- Groups : 36
- Computers :
- Desktops : 66
- Laptops : 9
The data : The data is stored in a CSV file called new_FakeCompany.csv. Each field is named as follows : field01,field02...
The function : The function for creating the structure is in the FakeCompany.ps1 file. This function is based on a switch based on the first field of the CSV file.
switch ($Content.('field01')) {
'OU' {## Start create OU ##; Break }
'Groups' { ## Start create Groups ##; Break }
'Users' { ## Start create Users ##; Break }
'Computers' {## Start create Computers ##; Break }
Default {Write-Host "The file format is invalid"}
}To call the function, just specify with the argument -CSVFile the location of the CSV file.
PS C:\> FakeCompany -CSVFile C:\new_FakeCompany.csv Function FakeCompany
{
<#
.SYNOPSIS

.DESCRIPTION
