nagios无法登录

骑着蜗牛定乾坤

nagios已安装完成，浏览器输入ip/nagios，可以弹出登录界面，输入用户名和密码，一直弹出登录界面，无法登录，用户名和密码绝对没错，不知何解？

下面是nagios相关的配置：
nagios安装目录：/usr/local/nagios         版本：nagios-3.2.0
apache安装目录：/usr/local/apache2      版本：httpd-2.2.29
nagios插件安装目录：/usr/local/nagios   版本：nagios-plugins-1.4.14
php安装目录：/usr/local/php                版本：php-5.6.7


# vi /usr/local/apache2/conf/httpd.conf
Listen   80
User nagios
Group nagios
ServerName 127.0.0.1:80
##下面的是在文件结尾添加的
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
        <Directory "/usr/local/nagios/sbin">
        AuthType Basic
        Options ExecCGI
        AllowOverride None
        Order allow,deny
        Allow from all
        AuthName "Nagios Access"
        AuthUserFile /usr/local/nagios/etc/htpasswd.user
        Require valid-user
  </Directory>

   Alias /nagios "/usr/local/nagios/share"
        <Directory "/usr/local/nagios/share">
        AuthType Basic
        Options None
        AllowOverride None
        Order allow,deny
        Allow from all
        AuthName "nagios Access"
        AuthuserFile /usr/local/nagios/etc/htpasswd.user
        Require valid-user
        </Directory>

# vi /usr/local/nagios/etc/cgi.cfg
use_pending_states=1
use_authentication=1
default_user_name=test

authorized_for_system_commands=test
authorized_for_all_services=test

authorized_for_all_host_commands=test

# cat /usr/local/nagios/etc/htpasswd.user
test:ZSf031Cdvzzy2

#chown nagios:nagios /usr/local/nagios

iptables selinux全都关闭，httpd nagios重启过，浏览器缓存也清空过无数次，总是不能登录，一直弹出登录界面，第一次安装，求解
