Create bulk users in AD – Simple, using ADSI


Hello,

I thought I'd share one of the scripts I used while working on a customer scenario. I needed to create lot of users on a particular OU. I've used below script to create bulk users to fulfil that scenario:

 

#Get the connection.
$domain = [ADSI]"LDAP://RootDSE"
$domain_DN = $domain.Get("defaultNamingContext")
$localhost = $env:computername + ":389"

$domain_conn = [ADSI] "LDAP://$localhost/$domain_DN";

## For new OU
$readOU = read-host "What will be the name of new OU under $domain_DN ? Please take care of OU name restrictions and put in quotes if with space"
$ouList = $domain_conn.psbase.get_children()
$ouExists = $false

foreach ($mem in $ouLis)
{
 if($mem.name -eq $readOU)
 { $ouExists = $true;
  write-host "OU $readOU found - already exists"
 }
}
 
if(!$ouExists)
{
 $newOU = $domain_conn.Create("organizationalUnit", "ou=$readOU");
 $newOU.SetInfo();
}
else
{
 write-host "wow! $readOU is a good name for an OU, users will be created in this OU"
}

 

##For new Users in new OU

$ouPath = "ou=" + $readOU+"," + $domain_DN

$ou_conn= [ADSI] "LDAP://$localhost/$ouPath"

write-host "`nA prefix will be used to create number of users entered appending each number at the end. i.e. if the prefix is 'jadoo-' then users will be created as 'jadoo-0', 'jadoo-1', 'jadoo-2'.. and so on."

$prefix = read-host "`nWhat is the prefix for username?"
[int]$limit = read-host "`nHow many users do you want to create? "
$pass = read-host "`nEnter a common password for users"

for($i=0; $i -lt $limit; $i++)
{
 $userName =  $prefix + $i;
    $userCN = "cn=" + $userName;
 $objUser = $ou_conn.Create("user", $userCN);
 $objUser.Put("sAMAccountName", $userName);
 $objUser.SetInfo();
 $objUser.SetPassword($pass)
 $objUser.psbase.InvokeSet("AccountDisabled", $false);
 $objUser.SetInfo();
}

## display OU and users created

$ou_conn
$ou_conn.psbase.get_children() | select distinguishedName

 

 

I hope this will be helpful for those wanting to quickly create bulk users for testing some scenario in Lab.
