This little guy is a simple dynamic parameter resource for you all. Take a look at my previous blog post about how these parameters work. Totally worth adding these things to your scripts. This script is simple, it uses the add-adgroupmemeber and dynamic parameters to help pad against mistakes.
The Script
function Set-SHDADGroupMemebers {
[cmdletbinding()]
param (
[parameter(mandatory=$true)][validateset('Add','Remove')][string]$Action,
[securestring]$Credential,
[switch]$Output
)
DynamicParam {
# Set the dynamic parameters' name
$ParamName_portgroup = 'Group'
# Create the collection of attributes
$AttributeCollection = New-Object System.Collections.ObjectModel.Collection[System.Attribute]
# Create and set the parameters' attributes
$ParameterAttribute = New-Object System.Management.Automation.ParameterAttribute
$ParameterAttribute.Mandatory = $true
# Add the attributes to the attributes collection
$AttributeCollection.Add($ParameterAttribute)
# Create the dictionary
$RuntimeParameterDictionary = New-Object System.Management.Automation.RuntimeDefinedParameterDictionary
# Generate and set the ValidateSet
$arrSet = (Get-ADGroup -Filter *).name
$ValidateSetAttribute = New-Object System.Management.Automation.ValidateSetAttribute($arrSet)
# Add the ValidateSet to the attributes collection
$AttributeCollection.Add($ValidateSetAttribute)
# Create and return the dynamic parameter
$RuntimeParameter = New-Object System.Management.Automation.RuntimeDefinedParameter($ParamName_portgroup, [string], $AttributeCollection)
$RuntimeParameterDictionary.Add($ParamName_portgroup, $RuntimeParameter)
# Set the dynamic parameters' name
$ParamName_datastore = 'Username'
# Create the collection of attributes
$AttributeCollection = New-Object System.Collections.ObjectModel.Collection[System.Attribute]
# Create and set the parameters' attributes
$ParameterAttribute = New-Object System.Management.Automation.ParameterAttribute
$ParameterAttribute.Mandatory = $true
# Add the attributes to the attributes collection
$AttributeCollection.Add($ParameterAttribute)
# Generate and set the ValidateSet
$arrSet = (Get-ADUser -Filter *).name
$ValidateSetAttribute = New-Object System.Management.Automation.ValidateSetAttribute($arrSet)
# Add the ValidateSet to the attributes collection
$AttributeCollection.Add($ValidateSetAttribute)
# Create and return the dynamic parameter
$RuntimeParameter = New-Object System.Management.Automation.RuntimeDefinedParameter($ParamName_datastore, [string], $AttributeCollection)
$RuntimeParameterDictionary.Add($ParamName_datastore, $RuntimeParameter)
return $RuntimeParameterDictionary
}
begin{
$Group = $PsBoundParameters[$ParamName_portgroup]
$username = $PsBoundParameters[$ParamName_datastore]
}
process {
if ($PSBoundParameters.ContainsKey('Credential')) {
if ($Action -like "Add") {
Add-ADGroupMember -Identity $group -Members $username -Credential $Credential
} elseif ($Action -like "Remove") {
Remove-ADGroupMember -Identity $group -Members $username -Credential $Credential
} else {
Get-ADGroupMember -Identity $group -Credential $Credential
}
} else {
if ($Action -like "Add") {
Add-ADGroupMember -Identity $group -Members $username
} elseif ($Action -like "Remove") {
Remove-ADGroupMember -Identity $group -Members $username
} else {
Get-ADGroupMember -Identity $group
}
}
}
end {
if ($Output) {
if ($PSBoundParameters.ContainsKey('Credential')) {
Get-ADGroupMember -Identity $Group -Credential $Credential
} else {
Get-ADGroupMember -Identity $group
}
}
}
}
Example 1
Set-SHDADGroupMemebers -Action Add -Group Administrators -Username Adam.Long -Output
Adds Adam.Long to the administrators group. Then it outputs all the users inside that group.
Example 2
Set-SHDADGroupMemebers -Action Remove -Group Administrators -Username Adam.Long
Removes Adam.Long from the Administrators group without outputting any additional information.

I have been through a few years of hard times with mental health. Mental health is no joke. Mental health is Health and that’s final. This Mental Health Links page is designed to help those struggling with mental health. In the IT field, over 89% of techs feel like it’s a requirement to work over. This is not a safe way to live. So, let’s fight this fight together. If you have any links feel free to message me with them.

I wanted to share a little script that has changed the world at my current company. It’s a simple password email notification script. What it does is grabs the users’ whos passwords about to expire. Then it emails that user with instructions on how to reset their password. Then it sends an email to the user’s manager with a list of when the user’s password will expire. Then finally it sends an email to another person with a complete list of all expiring users and when they will expire. After the user hits zero, the script no longer cares about that person. This is to prevent lots of headaches in the long run with on leave and whatnots. The best thing to do is to set up a scheduled task on a server with rsats. The computer will also need a relay setup on the exchange server.
The Script
param (
[parameter(Helpmessage = "Return Email", Mandatory = $true)][string]$ReturnEmail,
[parameter(Helpmessage = "Email Sent to IT", Mandatory = $true)][string]$ITEmail,
[parameter(Helpmessage = "Mail Server", Mandatory = $true)][string]$MailServer,
[parameter(Helpmessage = "Employee Organizational Unit", Mandatory = $true)][string]$EmployeeOU,
[parameter(Helpmessage = "Training Link", Mandatory = $true)][string]$TrainingLink,
[parameter(Helpmessage = "Training Link", Mandatory = $true)][string]$DaysWithinExpiration
)
$MaxPwdAge = (Get-ADDefaultDomainPasswordPolicy).MaxPasswordAge.Days
$expiredDate = (Get-Date).addDays(-$MaxPwdAge)
$emailDate = (Get-Date).addDays( - ($MaxPwdAge - $DaysWithinExpiration))
$ExpiredUsers = Get-ADUser -Filter { (PasswordLastSet -lt $emailDate) -and (PasswordLastSet -gt $expiredDate) -and (PasswordNeverExpires -eq $false) -and (Enabled -eq $true) } -Properties DisplayName, PasswordNeverExpires, Manager, PasswordLastSet, Mail, "msDS-UserPasswordExpiryTimeComputed" -SearchBase "$EmployeeOU" | Select-Object DisplayName, samaccountname, manager, PasswordLastSet, @{name = "DaysUntilExpired"; Expression = { $_.PasswordLastSet - $ExpiredDate | Select-Object -ExpandProperty Days } }, @{name = "EmailAddress"; Expression = { $_.mail } }, @{Name = "ExpiryDate"; Expression = { [datetime]::FromFileTime($_."msDS-UserPasswordExpiryTimeComputed") } } | Sort-Object PasswordLastSet
