As we are aware that ConfigMgr'07 admin full access provide a lot of privilege to manage all desktop in an enterprise so it’s critical to manage the ConfigMgr admin access with role based security model. And recently we have introduced the new security group model for managing ConfigMgr operations and having least admin access on ConfigMgr as role based which is very much align to ConfigMgr out of box security classes.
Below are the list of sample security groups we provisioned in AD and same configured in ConfigMgr admin console with equivalent access rights to manage the role based security in ConfigMgr'07.
Hope this helps in your planning for securing ConfigMgr'07 admin access with role based security model.
