老师你好，创建用户报这个权限不足的错怎么办
2016-02-04T23:11:06.776+0800 E QUERY Error: couldn't add user: not authorized on test to execute command { createUser: "test1", pwd: "xxx", roles: [ { role: "read", db: "test" } ], digestPassword: false, writeConcern: { w: "majority", wtimeout: 30000.0 } } 会报这个错啊. mongo版本3.0.7 ,有人知道吗
