# Enabling SSO (single sign on)

Parallels DaaS automatically enables Single Sign-On (SSO) in multi-session environments at the host pool level during deployment. SSO allows users to log in once using their primary credentials (e.g., corporate Entra-ID) and gain seamless access to virtual desktops without repeated authentication prompts.

Follow these steps to enable Single Sign-On (SSO) for Parallels DaaS using Microsoft Graph.

#### 1. Sign in to Azure

Use the following command to sign in to Azure with your tenant context and then set the desired subscription context:

`Connect-AzAccount -Tenant "<your-tenant-id>" -UseDeviceAuthentication Set-AzContext -SubscriptionId "<your-subscription-id>" -Tenant "<your-tenant-id>"`

#### 2. Prepare your environment

Ensure that the PowerShell execution policy allows local scripts:

`Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser`

#### 3. Install the required Microsoft Graph modules

Install the Microsoft Graph PowerShell module:

`Install-Module Microsoft.Graph -Scope CurrentUser -Repository PSGallery -Force`

#### 4. Import necessary modules

Import the authentication and applications modules:

`Import-Module Microsoft.Graph.Authentication Import-Module Microsoft.Graph.Applications`

#### 5. Connect to Microsoft Graph

Connect using Microsoft Graph with the appropriate permissions:

`Connect-MgGraph -Scopes "Application.Read.All","Application-RemoteDesktopConfig.ReadWrite.All" -Tenant "<your-tenant-id>"`

#### 6. Enable SSO on required service principals

Fetch the service principal IDs for the following two apps:

* **Microsoft AVD Client**: App ID `a4a365df-50f1-4397-bc59-1a1564b8bb9c`
* **Windows Cloud Login**: App ID `270efc09-cd0d-444b-a71f-39af4910ec45`

Then update their remote desktop security configuration:

`$MSRDspId = (Get-MgServicePrincipal -Filter "AppId eq 'a4a365df-50f1-4397-bc59-1a1564b8bb9c'").Id $WCLspId = (Get-MgServicePrincipal -Filter "AppId eq '270efc09-cd0d-444b-a71f-39af4910ec45'").Id Update-MgServicePrincipalRemoteDesktopSecurityConfiguration -ServicePrincipalId $MSRDspId -IsRemoteDesktopProtocolEnabled Update-MgServicePrincipalRemoteDesktopSecurityConfiguration -ServicePrincipalId $WCLspId -IsRemoteDesktopProtocolEnabled`

#### 7. Verify SSO is enabled

You can verify the settings using:

`Get-MgServicePrincipalRemoteDesktopSecurityConfiguration -ServicePrincipalId $MSRDspId Get-MgServicePrincipalRemoteDesktopSecurityConfiguration -ServicePrincipalId $WCLspId`
