Granting permissions to users based on Group Membership with PowerShell

Hello,

Question: Have you ever had to perform a task for multiple users like granting a permission, policy or something else? and did you do it manually?

I can honestly say I have and it was so time consuming, especially when we have free tools available to use to perform theses actions within seconds/minutes instead of hours/days.

I have generated a script below which I have created to grant a Skype for Business Online policy to a number of users based on their Group Membership. Before you run this script the following assumputions will be made.

  • You have a basic understanding of PowerShell Scripting
  • You have modified all locations shown with ‘#########’ to your requirements

For the below script I have left in ‘IMOnly’ to show exactly what this script is designed to achieve. If a User doesnt have the IMOnly policy they will be granted the policy but if a User already has IMOnly granted. The script will skip the user and generate an output on screen plus to a definited .txt file before moving onto the next user.


clear-host
# Define Service Account
$username = '#########'
$password = '#########'
$pass = Convertto-Securestring -String $password -asPlaintext -Force
$credential = New-Object -TypeName System.Management.Automation.PScredential -ArgumentList ($username, $pass)

# Connect to Office 365
Import-Module MSOnline
Connect-MsolService -Credential $credential

# Connect to Skype for Business Online
Import-Module -Name SkypeOnlineConnector
$sfboSession = New-CsOnlineSession -Credential $credential
Import-PSSession -Session $sfboSession -AllowClobber

# Get Group Members
Get-MsolGroupMember -GroupObjectId '#########' | export-csv -Path $env:HOMEDRIVE\INSTALL\#########.csv

# Import Users
$csv = Import-Csv -Path $env:HOMEDRIVE\#########\#########.csv

# Assign CsClientPolicy
Foreach ($row in $csv) {
If(Get-CsOnlineUser -Identity $row.EmailAddress | Where-object {$_.ClientPolicy -notcontains 'IMOnly'})
{
Grant-CsClientPolicy -Identity $row.EmailAddress -PolicyName 'IMOnly'
}
else
{
Write-Host -ForegroundColor Yellow $row.EmailAddress "Skipped User"
get-csonlineuser -id $row.EmailAddress | Where-object {$_.ClientPolicy -contains 'IMOnly'} | select-object DisplayName,ClientPolicy | out-file -FilePath $env:HOMEDRIVE\INSTALL\groupuserenbled.txt
}
}

You can also complete this command for On-Premises users by modifying the script to use Get-ADGroupMember as shown below.


# Get Group Members
Get-ADGroupMember -Identity '#########' | export-csv -Path $env:HOMEDRIVE\INSTALL\#########.csv

This script can be modified to complete other provisioning based on Group Membership, just copy and paste into PowerShell ISE and make the necessary changes
