freeradius认证后出错 用户名前面出现一段莫名其妙的字符串

xukai2013

错误开始出现在红字部分，蓝字是错误

1.在ubuntu上安装了freeradius 和mysql。
本地认证可以成功：radtest hanna 123456 localhost 0 testing123

2.配置了mysql，添加了用户：xukai  密码：123456，代码如下：
mysql -uroot -p123456 radius
        INSERT INTO radcheck (username,attribute,op,VALUE) VALUES  ('xukai','Cleartext-Password',':=','123456');
        将用户hanna加入VIP1用户组
        INSERT INTO radusergroup (username,groupname) VALUES  ('demo','VIP1');
        限制同时登陆人数，注意是在radgroupcheck表
        INSERT INTO radgroupcheck (groupname,attribute,op,VALUE)  VALUES ('normal','Simultaneous-Use',':=','1');
        认证回应reply
        INSERT INTO radgroupreply (groupname,attribute,op,VALUE)  VALUES ('VIP1','Auth-Type',':=','Local');
        INSERT INTO radgroupreply (groupname,attribute,op,VALUE)  VALUES ('VIP1','Service-Type',':=','Framed-User');
        INSERT INTO radgroupreply (groupname,attribute,op,VALUE)  VALUES ('VIP1','Framed-Protocol',':=','PPP');
        INSERT INTO radgroupreply (groupname,attribute,op,VALUE)  VALUES ('VIP1','Framed-MTU',':=','1500');
        INSERT INTO radgroupreply (groupname,attribute,op,VALUE)  VALUES ('VIP1','Framed-Compression',':=','Van-Jacobson-TCP-IP');

配置了交换机支持802.1X，选用eap方法

3.在xclient客户端登录后，server认证失败，代码如下

配置的时候，就是用户名xukai，怎么显示的是一堆字符串和用户名呢？
哪位朋友了解吗？谢谢啦
