【 使用环境 】测试环境
【 OB or 其他组件 】obclient和oblogproxy和ob
【 使用版本 】oblogclient:1.1.2 oblogproxy:2.02bp1 ob
【问题描述】使用obclient官网实例代码，其中setRsList这个写的是ob的全部ip(10.1.3.81,10.12.3.45,10.12.3.44)，setUsername写的是非系统租户用户cm_member@obcms，setSysUsername写的是root@sys用户名，非租户是obcms，setClusterUrl没有设置，然后连接的时候会报鉴权失败，
看日志是使用cm_member去81鉴权失败，但是用obclient -ucm_member@obcms在3个ip上都可以完成登录的，但是如果setUsername写成root@sys就可以通过鉴权
【复现路径】问题出现前后相关操作
