Hello
Thank you for posting in Q&A forum.
gMSA is mainly used in local environments and integrated with Active Directory. It cannot be used directly with Azure AD.
The synchronization between local Active Directory and Azure AD requires the use of the Azure AD Connect tool. Azure AD Connect does not involve the synchronization of gMSA. The features and management of gMSA are still limited to the scope of local AD and cannot be directly extended to Azure AD.
In the Azure cloud environment, it is recommended to use Azure Managed Identities (AMI) when handling authentication and access control of services and applications.
I hope the information above is helpful.
Best Regards,
Yanhong Liu
