I'm attempting to import a bunch of users from a csv into local users, then add them to a group. The username and password are set to a mac address, this is for mac authentication.

The import works fine. All users are created but it just will not add them to a local group.

( I based my work off of this post. )

My guess is that it's not concatenating correctly and thats the issue, but I'm not really sure. I've done very little with powershell.


$objgroup = [ADSI]"WinNT://RadiusSVR/TEST,group"
$target = [ADSI]"WinNT://RadiusSVR"

Import-Csv testlist1.csv | ForEach-Object {
$newuser = $target.Create("user", $_.MAC)
$newuser.FullName = ($_.NAME)
$newuser.psbase.InvokeSet('AccountDisabled', $false)

$objuser = [ADSI]"WinNT://RadiusSVR/" + $_.MAC

Try using a subexpression.

$objuser = [ADSI]"WinNT://RadiusSVR/$($_.MAC)"

Tried that. I get type mismatch errors.

I got it working by using net commands instead. I've tried like a dozen suggestions to get this to work and at this point I don't believe it can.

Here is the error I get when I try that.

Looks to me like it's balking at
$objuser = [ADSI]"WinNT://RadiusSVR/" + $_.MAC

'op_Addition' makes the '+' in + $_.MAC jump out at me.
Maybe enclose it all in ()
( [ADSI]"WinNT://RadiusSVR/" + $_.MAC )
Or maybe try
Depending on the PS version you are using.

If using POSH3 or higher perhaps try creating a Desired State Push Script that says what accounts and groups must be present and what memberships each group must have?
