Active Roles now allows you to administer group Managed Service Accounts.
Introduced in Windows Server 2012, group Managed Service Account (gMSA) is a domain security principal whose password is managed by Windows Server 2012 domain controllers and can be retrieved by multiple systems running Windows Server 2012. Having Windows services use gMSA as their logon account minimizes the administrative overhead by enabling Windows to handle password management for service accounts. Group Managed Service Accounts provide the same functionality as Managed Service Accounts introduced in Windows Server 2008 R2 and extend that functionality over multiple servers.
Active Roles 7.4 version supports usage of Group Managed Service Account as Active Roles Service Account. For more information about using gMSA as a service account, see Configuring gMSA as an Active Roles Service account in the Active Roles Administration Guide.
