Jaspersoft Studio MongoDB连接身份验证失败

我正在尝试将Jaspersoft Studio 6.2.0连接到MongoLab上托管的MongoDB数据库（mongod版本：3.0.7）。

使用连接URI：

 mongodb://ds012345-a0.mongolab.com:12345,ds012345-a1.mongolab.com:12345/mydb?replicaSet=rs-ds012345

测试适配器时出现以下异常：

net.sf.jasperreports.engine.JRException: com.mongodb.CommandFailureException: { "serverUsed" : "ds012345-a0.mongolab.com:12345" , "ok" : 0.0 , "errmsg" : "auth failed" , "code" : 18}
