Server administrators must be a valid user, service principal, or security group in the Microsoft Entra ID for the tenant in which the server resides. You can use Analysis Services Admins for your server in Azure portal, Server Properties in SSMS, PowerShell, or REST API to manage server administrators.
When adding a security group, use obj:groupid@tenantid. Service principals are not supported in security groups added to the server administrator role.
If server firewall is enabled, server administrator client computer IP addresses must be included in a firewall rule. To learn more, see Configure server firewall.
