Change the password policy of your Azure AD accounts

by Jan de Vries in  , ,

For our automated deployments we have several Azure Organizational accounts in place. These are created within the Azure Active Directory.

Because these accounts are meant for services, we don’t want them to inherit the default password policy for renewing their passwords every X days. Lucky for us, you can configure this via PowerShell. A short how-to is written on MSDN.

The thing that isn’t written (or referenced) over there is how to run the MSOL cmdlets.

I kept getting the messages The term 'Set-MsolUser' is not recognized. By searching a bit on this error I found a thread on the Office365 community forums where someone mentioned the “Microsoft Online Service Module for Windows PowerShell”. This set me off to searching in the right direction. Apparently you need to install a (new/extra) PowerShell module on your system in order to use the MSOL cmdlets. These cmdlets are part of the Office365 and Exchange Online services. A page with download links is provided by Microsoft Support. They provide a link to the Microsoft Online Service Sign-in Assistant for IT Professionals and the Azure Active Directory Module for Windows PowerShell (32-bit and 64-bit).

Once installed, you are finally able to use the MSOL cmdlets. Keep in mind though, you have to connect to the MSOL services first using the connection cmdlet.

Connect-MsolService -Credential $azureADCredentials

After connecting to the service, you can change the service account it’s password behavior to Password Never Expires.

For reference, this is the script I’ve used when changing the service account password policies:

function Set-CustomerAzureSubscription($subscriptionName)
{
    $azureSubscriptionSecurePassword  = ConvertTo-SecureString -String $azureSubscriptionPassword -AsPlainText -Force
    $azureCredentials = New-Object System.Management.Automation.PSCredential($azureSubscriptionUsername, $azureSubscriptionSecurePassword)

    Get-AzureAccount
    Add-AzureAccount -Credential $azureCredentials
    Get-AzureSubscription | % { Write-Host "Customer subscription: $($_.SubscriptionName)."}
    Write-Host "Selecting $($subscriptionName) as default Customer subscription."
    Select-AzureSubscription -SubscriptionName "$($subscriptionName)"
}
function Set-PasswordNeverExpiresForServiceAccounts($serviceAccountUsername, $serviceAccountPassword)
{
    $azureADCredentialsSecurePassword  = ConvertTo-SecureString -String $serviceAccountPassword -AsPlainText -Force
    $azureADCredentials = New-Object System.Management.Automation.PSCredential($serviceAccountUsername, $azureADCredentialsSecurePassword)

    Write-Host "Connecting to MSOL"
    Connect-MsolService -Credential $azureADCredentials
    Write-Host "Password never expires status of $($serviceAccountUsername)"
    Get-MSOLUser -UserPrincipalName $serviceAccountUsername | Select PasswordNeverExpires
    Write-Host "Setting password never expires status of $($serviceAccountUsername) to 'true'"
    Set-MsolUser -UserPrincipalName $serviceAccountUsername -PasswordNeverExpires $true
    Write-Host "Password never expires status of $($serviceAccountUsername)"
    Get-MSOLUser -UserPrincipalName $serviceAccountUsername | Select PasswordNeverExpires
}
Set-CustomerAzureSubscription $devSubscription
Set-PasswordNeverExpiresForServiceAccounts $devServiceAccount $devPassword
Set-CustomerAzureSubscription $accSubscription
Set-PasswordNeverExpiresForServiceAccounts $accServiceAccount $accPassword
Set-CustomerAzureSubscription $prodSubscription
Set-PasswordNeverExpiresForServiceAccounts $prodServiceAccount $prodPassword
