LDAP是一款轻量级目录访问协议（Lightweight Directory Access Protocol，简称LDAP），属于开源集中账号管理架构的实现，且支持众多系统版本，被广大互联网公司所采用。

一般会将svn，git，VPN，等一系列账号做一个统一管理，ldap是非常好的选择

1.启动ldap和Web UI管理工具,如果想通过浏览器控制 OpenLDAP ，可以使用 phpldapadmin

#启动openladp
docker run \
--restart=always \
-v /etc/localtime:/etc/localtime:ro \
-p 389:389 \
-p 636:636 \
--name myopenldap \
--env LDAP_ORGANISATION="ilovesally" \
--env LDAP_DOMAIN="ilovesally.com" \
--env LDAP_ADMIN_PASSWORD="123456" \
-v /openldap/data:/var/lib/ldap \
-v /openldap/conf:/etc/ldap/slapd.d \
--detach osixia/openldap:1.5.0

#启动phpldapadmin(管理工具)
docker run \
--restart=always \
-v /etc/localtime:/etc/localtime:ro \
-p 1111:80 \
--name myphpldapadmin \
--env PHPLDAPADMIN_HTTPS=false \
--env PHPLDAPADMIN_LDAP_HOSTS=10.10.20.236 \
--detach osixia/phpldapadmin:0.9.0

由于新建的ldap是没有初始化数据的，所以就需要我们手工创建初始化数据

具体使用方法，可以参考：https://wiki.shileizcc.com/confluence/pages/viewpage.action?pageId=39223519

常用的ldif文件操作

a.企业架构

b.创建一个用户,并把其加入到某个组中

#创建用户密码
root@6c3f3669b4bf:/var/lib/ldap/ldif# slappasswd -h {SHA} -s 111111
{SHA}PU8r8H3BvjiyDNbkaUmhBx+dDj0=

#创建导入文件
root@6c3f3669b4bf:/var/lib/ldap/ldif# cat addperson.ldif 
dn: uid=luzhihua,ou=devops,ou=amoy,ou=qzing,dc=ilovelluvia,dc=com
uid: luzhihua
cn: luzhihua
sn: luzhihua
givenName: luzhihua
displayName: luzhihua
objectClass: posixAccount
objectClass: top
objectClass: person
objectClass: shadowAccount
objectClass: inetOrgPerson
objectclass: organizationalperson
uidNumber: 1000
gidNumber: 1000
loginShell: /bin/bash
homeDirectory: /home/luzhihua
userPassword: {SHA}PU8r8H3BvjiyDNbkaUmhBx+dDj0=
shadowLastChange: 17654

#导入

adding new entry "uid=luzhihua,ou=devops,ou=amoy,ou=qzing,dc=ilovelluvia,dc=com"


#创建导入文件
cat >>add_group.ldif<<EOF

EOF

#导入

memberOf: cn=projectA,ou=qzing,dc=ilovelluvia,dc=com

 

2.制作nginx镜像，加上ldap模块，其中nginx-auth-ldap模块的下载地址是：https://github.com/kvspb/nginx-auth-ldap.git

[root@10-10-20-236 nginx]# cat Dockerfile
FROM centos:7.9.2009

MAINTAINER teddylu<[email protected]>

# 安装软件
RUN yum -y update && yum -y install epel-release openssl openssl-devel zlib zlib-devel pcre pcre-devel glibc glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel wget libevent-devel libevent uuid-devel uuid gmake libxml2 libxml2-devel  libxslt-devel GeoIP GeoIP-devel GeoIP-data gcc gdb strace gcc-c++ autoconf unzip openldap openldap-devel

# 创建用户
#RUN groupadd teddylu
#RUN useradd -g teddylu teddylu -s /bin/false

# 定义Nginx版本号
ENV VERSION 1.21.1

# 下载并解压文件
RUN mkdir -p /soft && cd /soft && wget http://nginx.org/download/nginx-$VERSION.tar.gz && tar xf nginx-$VERSION.tar.gz

# 创建安装目录
ENV NGINX_HOME /application/nginx-1.21.1
RUN mkdir -p $NGINX_HOME
#RUN chown -R teddylu:teddylu $NGINX_HOME

ADD nginx-auth-ldap-master.zip /soft
RUN cd /soft/ && unzip nginx-auth-ldap-master.zip

# 进入解压目录
WORKDIR /soft/nginx-$VERSION
# 编译安装
RUN ./configure \
    --user=root \
    --group=root \
    --prefix=$NGINX_HOME \
    --with-http_ssl_module \
    --with-http_v2_module \
    --with-threads \
    --with-stream \
    --with-stream_realip_module \
    --with-stream_ssl_module \
    --with-stream_ssl_preread_module \
    --with-http_realip_module \
    --add-module=/soft/nginx-auth-ldap-master \
    --with-http_gzip_static_module \
    --with-http_stub_status_module
RUN make && make install

# 设置环境变量
ENV PATH /application/nginx-1.21.1/sbin:$PATH

# 暴露端口
EXPOSE 80
EXPOSE 443

# 清理压缩包与解压文件
RUN rm -rf /soft
CMD $NGINX_HOME/sbin/nginx -g 'daemon off;' -c $NGINX_HOME/conf/nginx.conf

3.启动nginx(注意需要提前将/application/nginx-1.21.1复制到宿主机中)

docker run \
--name mynginx-ldap \
--restart=always \
-v /etc/localtime:/etc/localtime:ro \
-p 80:80 \
-p 443:443 \
-v /application/nginx-1.21.1/:/application/nginx-1.21.1/ \
-d mynginx-ldap:v1.0

4.nginx配置文件(window2012的AD安装跳过)

#这个是window2012AD的配置   
ldap_server openldap {
       url ldap://10.10.20.72:389/ou=it,dc=ilovesally,dc=xyz?sAMAccountName?sub?(objectClass=person);
       binddn "ilovesally\Administrator";
       binddn_passwd xmasp1@admin
       connections 10;
       satisfy any;
       group_attribute memberOf;
       group_attribute memberuid;
       group_attribute uniquemember;     
       group_attribute it;
       group_attribute_is_dn on;
       require valid_user;
     }


#这个是openLDAP的配置
       url ldap://10.10.20.236:389/dc=ilovesally,dc=com?uid?sub?(objectClass=person);
       binddn "cn=admin,dc=ilovesally,dc=com";
       binddn_passwd "123456";

#虚拟机配置（这里做了一个反向代理）
[root@10-10-20-236 conf]# cat vhosts/mkdocs.conf 
server {
        listen       80;
        server_name  localhost;

        location / {
        proxy_pass http://10.10.20.236:9999;
	auth_ldap "LDAP Authentication!!!!!";
    	auth_ldap_servers openldap;
        proxy_set_header   Host $host;
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Host $server_name;
        proxy_read_timeout  1200s;
        }
    }

5.看实际效果,一些web服务需要身份验证，这个ldap是非常不错的实现方式

 

6.自助修改或重置密码服务Self Service Password

Self Service Password是一个PHP应用程序，允许用户在LDAP目录中更改其密码。
该应用程序可以在标准LDAPv3目录（OpenLDAP，OpenDS，ApacheDS，389 DS，RHDS， Sun Oracle DSEE，Novell等）以及Active Directory上。
它具有以下功能：
Samba模式更改Samba密码
活动目录模式
本地密码策略：
最小/最大长度
禁止字符
大写，小写，数字或特殊字符计数器
重用旧密码检查
复杂度（不同类别的字符）
帮助信息
按问题重置
通过邮件重置（通过邮件发送令牌）
通过短信重置（通过外部电子邮件2短信服务）
验证码（Google API）
更改密码后的邮件通知

docker run \
--restart=always \
-v /etc/localtime:/etc/localtime:ro \
-p 1234:80 \
--name myself-service-password \
-v /ssp/conf/:/var/www/conf \
-d ltbproject/self-service-password:1.4.3

7.svn使用ldap登录(AD域控)

#安装软件
yum install -y subversion cyrus-sasl cyrus-sasl-lib cyrus-sasl-plain


#修改sasl的用户验证方式为ldap
cp /etc/sysconfig/saslauthd /etc/sysconfig/saslauthd.save
sed -i 's/MECH=pam/MECH=ldap/' /etc/sysconfig/saslauthd


#修改sasl配置文件/etc/saslauthd.conf

cat >>/etc/saslauthd.conf<<EOF

ldap_restart: yes
ldap_scope: sub
ldap_use_sasl: no
ldap_start_tls: no
ldap_version: 3
ldap_auth_method: bind
ldap_mech: DIGEST-MD5
ldap_filter:sAMAccountName=%u
ldap_password_attr:userPassword
ldap_timeout: 10
ldap_cache_ttl: 30
ldap_cache_mem: 32786
EOF

#重启sasl服务以应用配置文件并测试是否通过
systemctl restart saslauthd.service
testsaslauthd -u user -p 'password' 

[root@10-10-20-237 ~]# testsaslauthd -u luzhihua -p 'zxc123?!'
0: OK "Success."

#修改SVN的sasl配置文件/etc/sasl/svn.conf
cat >>/etc/sasl2/svn.conf<<EOF
pwcheck_method:saslauthd #用户验证方法

EOF

#修SVN的配置并重启
vim /yourrepository/conf/svnserve.conf  	
[general]
anon-access = none
auth-access = write
#password-db = passwd 				#关闭passwd
authz-db = authz 			        #如果要对版本库进行权限控制，开启authz
[sasl]
use-sasl = true 				#开启sasl用户验证
