【help】进不了tomcat的管理界面!!!

http://localhost:8080/admin/
我输入用户 密码 tomcat  后
报错:
type Status report
message Access to the requested resource has been denied
description Access to the specified resource (Access to the requested resource has been denied) has been forbidden.

我的tomcat-users.xml文件
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>
</tomcat-users>

我的tomcat是5.0.28的,直接解包的,不是安装的

<user username="tomcat" password="tomcat" roles="tomcat,admin,manage"/>
我自己增加了两行role,
<role rolename="manage"/>
  <role rolename="admin"/>
同时修改了
<user username="tomcat" password="tomcat" roles="tomcat,admin,manage"/>
就可以了,
谢谢二楼的,这是为什么啊,是固有的特性?
这个表示
用户:tomcat
密码:tomcat
可以操作:
tomcat admin manage
