Hi @ali ali,
Below ,a microsoft article which confirm that GMSA is supported by Azure AD connect.
Azure AD Connect: Accounts and permissions
GMSA will still supported by the future versions ,because Microsoft recommend to use GMSA instead of standard user domain, to symplify passoword management for service account and avoid to have Passowrd never expired.
the goal of this , to let the machine manage it self to renew de password
When you use GMSA as service account instead of standard user , the password will be changed managed automatically. It's recommended approach.
