Pass Multiple Values in Parameter to Custom Command through Powershell

Question

Hello,

I'm trying to execute a custom command through a Powershell script, but I'm struggling to pass multiple values to an AD Object Picker parameter. Is there a way to do that? I've tried passing it as an array of distinguished names, as a string with each one separated by semicolons (which matches the character used to separate them in the parameter configuration), and as a string with each one separated by new lines, but I get the errors "Input string was not in a correct format," or "DN was invalid." Here's my code if it helps:

# Connect to the Adaxes service
$admNS = New-Object "Softerra.Adaxes.Adsi.AdmNamespace"
$admService = $admNS.GetServiceDirectly("localhost")

# Bind to the custom command
$commandDN = "<distinguished name of the custom command>"
$command = $admService.OpenObject("Adaxes://$commandDN", $NULL, $NULL, 0)

# define parameter values
$groupName = "GroupName"
$owners    = "Owner1DistinguishedName", "Owner2DistinguishedName", "Owner3DistinguishedName"
$members   = "Member1DistinguishedName", "Member2DistinguishedName", "Member3DistinguishedName"

# Specify the arguments for command execution
$commandArguments = $command.CreateArguments()
$commandArguments.SetParameterValue("param-groupName", $groupName) # edit box parameter
$commandArguments.SetParameterValue("param-owners", $owners)       # AD object picker parameter
$commandArguments.SetParameterValue("param-members", $members)     # AD object picker parameter

# Run the custom command
$obj = $admService.OpenObject("Adaxes://<distinguished name of OU>", $NULL, $NULL, 0)
$obj.ExecuteCustomCommand($command.CommandID, $commandArguments)

Thanks in advance!

Hello,

It has to be an array containing distinguished names (DNs) of the objects. Also, your script misses the line for loading the assembly. Finally, it should look like the following:

[Reflection.Assembly]::LoadWithPartialName("Softerra.Adaxes.Adsi")

# Connect to the Adaxes service
$admNS = New-Object "Softerra.Adaxes.Adsi.AdmNamespace"
$admService = $admNS.GetServiceDirectly("localhost")

# Bind to the custom command
$commandDN = "<distinguished name of the custom command>"
$command = $admService.OpenObject("Adaxes://$commandDN", $NULL, $NULL, 0)

# define parameter values
$groupName = "GroupName"
$owners = @("Owner1DistinguishedName", "Owner2DistinguishedName", "Owner3DistinguishedName")
$members = @("Member1DistinguishedName", "Member2DistinguishedName", "Member3DistinguishedName")

# Specify the arguments for command execution
$commandArguments = $command.CreateArguments()
$commandArguments.SetParameterValue("param-groupName", $groupName) # edit box parameter
$commandArguments.SetParameterValue("param-owners", $owners)       # AD object picker parameter
$commandArguments.SetParameterValue("param-members", $members)     # AD object picker parameter

# Run the custom command
$obj = $admService.OpenObject("Adaxes://<distinguished name of OU>", $NULL, $NULL, 0)
$obj.ExecuteCustomCommand($command.CommandID, $commandArguments)

If you get error messages using this approach, it means that there is something incorrect about working with the parameters in your custom command itself, not in the script executing the command. For example, if you need to add the target user to multiple groups selected in the parameter, the script in the custom command will look like below.

$separator = ";" # TODO: modify me

# Get parameter value
$parameterValue = $Context.GetParameterValue("param-owners")

# Add user to groups
foreach ($dn in $parameterValue.Split($separator))
{
    $group = $Context.BindToObjectByDN($dn)
    $group.Add($Context.TargetObject.AdsPath)
}

In the script, the $separator variable specifies the character used to separate object DNs in the parameter. It must match that specified in the parameter settings.

That worked. I also had to fix an error in how I was handling the parameter in the custom command script. Thanks for you help!
