The specified user role is not valid or no longer exists.

The SelfServiceUser value is the only valid value for -UserRole in this situation.

_vmmServerConn = new ServerConnection(

                                            vmmserver.Address,

                                            vmmserver.Port,

                                            Microsoft.VirtualManager.Remoting.Profile.Administrator,

                                            vmmserver.Authority,    //注意System Center的版本语言，中文版就是管理员，

                                            new SecureCredential(

                                                vmmserver.UserName,

                                                vmmserver.Password.ToCharArray()),

                                            ServerConnection.InitializationStrategy.EagerInitialization,

                                            true,

                                            false

                                        );

所以，大家在配置链接vmm的数据库的字段时，英文版的

Authority=“administrator”
中文版：

Authority=“管理员”
