 * Assigning permissions to a service principal or to a GDAP user group in Microsoft Sentinel isn't supported in unified RBAC. If you need either capability, don't activate Sentinel in unified RBAC yet. Continue using Azure RBAC for Microsoft Sentinel.
 * The Microsoft Defender unified RBAC model only impacts the Microsoft Defender portal. It doesn't impact the [Microsoft Purview portal](https://purview.microsoft.com) or the [Exchange Admin Center](https://admin.exchange.microsoft.com).

Making permission changes in the Azure portal after unified RBAC is active for a workspace might lead to sync errors. If a sync error occurs, a notification appears on the **Permissions** page in the Defender portal with instructions on how to resolve it.
