nginx ldap模块使用

Posted 2023-04-18

参考技术A 1. 安装windows openldap服务

2. 通过ldap admin连接

3.  添加新的OU和uid

nginx配置如下

ldap_server testldap

#url ldap://192.168.137.1:389/dc=micmiu,dc=com?uid?sub?(&(objectClass=*));

        url ldap://192.168.137.1:389/dc=micmiu,dc=com?uid?sub?(objectClass=*);

        binddn "uid=Miumiu,ou=Tester,dc=micmiu,dc=com";

        binddn_passwd "111111";

        group_attribute memberuid;

        group_attribute_is_dn on;

        require valid_user;

     

    server

        listen 8000;

        server_name testldap_server;

        location /

            root html;

            index index.html index.htm;

            auth_ldap "Forbidden";

            auth_ldap_servers testldap;

         

   

之后再浏览器中输入用户名和密码：

Nginx 结合Python Ldap认证用于Kibana权限登陆

参考及依赖

https://github.com/nginxinc/nginx-ldap-auth
http://nginx.org/
nginx-1.14.2
http_auth_request_module
nginx-ldap-auth
python2.7
python-ldap

Nginx支持ldap

1. 部署nginx，注意需要http_auth_request_module支持

wget http://nginx.org/download/nginx-1.14.2.tar.gz
tar zxvf nginx-1.14.2.tar.gz
cd nginx-1.14.2
./configure --with-http_auth_request_module
make
make install
/usr/local/nginx/sbin/nginx

2. 配置nginx,注意ldap配置
   cat /usr/local/nginx/conf/nginx.conf

   
   user                  nobody nobody;
   worker_processes auto;
   #worker_cpu_affinity auto;

    #最最重要的ldap配置，请务必按照贵公司的ldap配置如下四项，我在这一步卡了好久，就是ldap配置不对

> ### Python Ldap认证

wget https://github.com/nginxinc/nginx-ldap-auth/archive/0.0.4.tar.gz
tar zxvf 0.0.4.tar.gz
python nginx-ldap-auth-daemon.py &

> ### 后端登陆跳转页面

默认页面只能测试，这里需要大概改下才能使用
vim backend-sample-app.py
python backend-sample-app.py &
backend-sample-app.py其中html=``````修改后如下
