Azure AD Custom Smart lockout

Question

Does the Custom smart lockout function lockout the Windows account if it exceed the lockout threshold (after the user had successfully created the profile in the Windows 10 machine). I tried applying it onto my AAD, it doesn't lockout the Windows account but it does lockout the user when user attempts to sign in to e.g. OneDrive etc.

Answer 1

Generally speaking, it does not, as it only applies to access to cloud resources. Use the corresponding controls in AD if you want to enforce a smart lockout in your on-premises environment.

The exception is when you are using pass-trough authentication, as authentication "touches" both Azure AD and on-premises servers, thus both the cloud and on-premises policies apply. You still need to have the on-premises policy configured if you want to enforce the account lock.

When the user is locked out or disabled or deleted from Azure AD, this user can still login to Azure AD joined device only for a limited time. When a user is deleted or disabled or locked in Azure AD, it's not immediately known to the Windows device. So, users who signed in previously can access the desktop with the cached username and password.

Typically, the device is aware of the user state in less than four hours. Then Windows blocks those users' access to the desktop. As the user is deleted or disabled in Azure AD, all their tokens are revoked. So they can't access any resources.

Deleted or disabled users who didn't sign in previously can't access a device. There's no cached username and password enabled for them.
