Executing multiple powershell commands via AD connector/PSExecute

Need to execute multiple powershell commands via the active directory shim powershell interface
For Eg:  In the below example account needs to be enabled for Lync.

$spwd = ConvertTo-SecureString "sjSD8jsdJAJDs" -AsPlainText -Force;
$mycreds = New-Object System.Management.Automation.PSCredential ("Client/pdsadmin", $spwd);
$sessionOption = New-PSSessionOption -SkipRevocationCheck:$true -SkipCACheck:$true -SkipCNCheck:$true;
$session = New-PSSession -ConnectionURI "https://dcsvr1.Client.ad.local/OcsPowershell" -Credential $mycreds -SessionOption $sessionOption;
Import-PsSession $session -AllowClobber;
enable-csuser -Identity "CN=lynctestu1,CN=Users,DC=Client,DC=ad,DC=local" -Registrar "dcsvr1.Client.ad.local" -SipAddress "sip:lynctestu1@Client.ad.local" -DomainController "dcsvr1.Client.ad.local";
Remove-PSSession $session;

The driver may report the following error :
Error completing powershell command.  ERROR:

The powershell commands have to be submitted as script block, by enclosing the commands within curly braces and then preceding with an ampersand as shown below
