 You can enforce Conditional Access policies such as require multi-factor authentication, require compliant or hybrid Azure AD joined device for the device running SSH client, and checking for risk before authorizing access to Linux VMs in Azure that are enabled with Azure AD login in.

 ## Using Azure Policy to ensure standards and assess compliance
 
-Use Azure Policy to ensure Azure AD login is enabled for your new and existing Linux virtual machines and assess compliance of your environment at scale on your Azure Policy compliance dashboard. With this capability, you can use many levels of enforcement: you can flag new and existing Linux VMs within your environment that don’t have Azure AD login enabled. You can also use Azure Policy to deploy the Azure AD extension on new Linux VMs that don’t have Azure AD login enabled, and remediate existing Linux VMs to the same standard. In addition to these capabilities, you can also use Azure Policy to detect and flag Linux VMs that have non-approved local accounts created on their machines. To learn more, review [Azure Policy](../../governance/policy/overview.md).

 ## Troubleshoot sign-in issues
 
 Some common errors when you try to SSH with Azure AD credentials include no Azure roles assigned, and repeated prompts to sign in. Use the following sections to correct these issues.
 
-### Missing application
-
-If the Azure Linux VM Sign-in application is missing from Conditional Access, use the following steps to remediate the issue:
-
-1. Check to make sure the application isn't in the tenant by:
-   1. Sign in to the **Azure portal**.
-   1. Browse to **Azure Active Directory** > **Enterprise applications**
-   1. Remove the filters to see all applications, and search for "VM". If you don't see Azure Linux VM Sign-in as a result, the service principal is missing from the tenant.
-
-Another way to verify it is via Graph PowerShell:
-
-1. [Install the Graph PowerShell SDK](/powershell/microsoftgraph/installation) if you haven't already done so. 
-1. `Connect-MgGraph -Scopes "ServicePrincipalEndpoint.ReadWrite.All","Application.ReadWrite.All"`
-1. Sign-in with a Global Admin account
-1. Consent to permission prompt
-1. `Get-MgServicePrincipal -ConsistencyLevel eventual -Search '"DisplayName:Azure Linux VM"'`
-   1. If this command results in no output and returns you to the PowerShell prompt, you can create the Service Principal with the following Graph PowerShell command:
-   1. `New-MgServicePrincipal -AppId ce6ff14a-7fdc-4685-bbe0-f6afdfcfa8e0`
-   1. Successful output will show that the AppID and the Application Name Azure Linux VM Sign-in was created.
-1. Sign out of Graph PowerShell when complete with the following command: `Disconnect-MgGraph`
