How to import multi-value reference with Granfeldt PowerShell MA?

Hi,

I am trying to import multi-value reference into FIM (Group object).

I can import all attributes from source SQL, except Multivalue reference (into members attribute on Group object).

I have defined schema like this:

$obj = New-Object -Type PSCustomObject
$obj | Add-Member -Type NoteProperty -Name "Anchor-axs_profid|String" -Value ""
$obj | Add-Member -Type NoteProperty -Name "objectClass|String" -Value "role"
$obj | Add-Member -Type NoteProperty -Name "name|String" -Value ""
$obj | Add-Member -Type NoteProperty -Name "member|Reference[]" -Value ""
$obj

On source attribute I have members defined in one attribute, divided by ",". 

Import script:

$Obj = @{}

    $Obj.Add("objectClass", "role")
    $Obj.Add("[DN]", "Role_"+$Object.$("axs_profid"))
    $Obj.Add("axs_profid",   $Object.$("axs_profid").ToString())
    $Obj.Add("name", $Object.$("name").ToString())
    if($Object.$("member").ToString() -ne "")
    {
        [string[]]$members = $Object.$("member").ToString().Split(',')
        $Obj.Add("member", $members)
    }

    $Obj
    

When Full import is triggered, I get following error for roles with multiple users:

FIM Sync = staging-error

The server encountered an unexpected error in the synchronization engine:

Forefront Identity Manager 4.1.3559.0"

If I change the script to return only first member:

$Obj.Add("member", $members[0])

import is successfull and I can see referenced member in Group.

I have also tried to specify DN for both users and roles with the same outcome.

$Obj.Add("[DN]", "Role_"+$Object.$("axs_profid"))

I am using the latest version of  PSMA: 5.5

Thanks for your help guys!
