Liferay登陆提示认证失败！
出现原因：开始配置Liferay数据库时，用的默认数据库。后来要求用mysql，所以就查了网上怎么更改数据库。后来查到一篇。
先在E:\Liferay6.2\liferay-portal-6.2-ce-ga4\tomcat-7.0.42\webapps\ROOT\WEB-INF\classes这个路径下创建一个portal-ext.properties。
里面的代码如下：
`hibernate.show_sql=true
MySQL
jdbc.default.driverClassName=com.mysql.jdbc.Driver
jdbc.default.url=jdbc:mysql://localhost:3306/lportal?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false
jdbc.default.username=root
jdbc.default.password=root
去掉用户第一次登录的时候的用户协议
terms.of.use.required=false
第一次登陆找回密码问题提示
users.reminder.queries.enabled=false
去掉公共页和私有页
layout.user.private.layouts.enabled=false
layout.user.public.layouts.enabled=false
让没有权限的portlet隐藏掉
layout.show.portlet.access.denied=false
Liferay的登录认证形式:使用屏幕名称
company.security.auth.type=screenName
用户的密码生成方式:表示生成的密码是静态的，默认密码为1
passwords.passwordpolicytoolkit.generator=static
passwords.passwordpolicytoolkit.static=1
用户密码加密方式
passwords.encryption.algorithm=SHA
javascript.fast.load=false

然后去登陆的时候，发现错误提示：认证失败!
解决方法：
**1.用户名写test，不写test@liferay
2.删除上面数据库配置文件中的company.security.auth.type=screenName**
在重启liferay就可以了！
