LDAP启用SSL/TLS
一、利用redhat-idm-console控制台生成ssl证书请求文件
[root@station2 ~]#redhat-idm-console
1、选择Manager Certificates后点击Request，生存证书请求文件
2、选择Request Certificaate manually后在Requestor information输入CA中心要求相关信息
#红色部分为CA中心定义的必须匹配的信息，其他为ldap服务器自身信息
3、在弹出对话框中输入Token Passwd（该密码为证书保护密码）的密码redhat，输入密码后next，选择“save to file”
#save to file文件即位证书请求文件dirsrv.crt（文件名自己定义）
4、将证书请求文件dirsrv.csr发送给CA中心，并由CA中心生成证书
[root@station2 ~]# scp dirsrv.csr 192.168.32.31:/root/.
root@192.168.32.31's password:
dirsrv.csr 100% 684 0.7KB/s 00:00
[root@server1 ~]# openssl ca -in dirsrv.csr -out dirsrv.crt
Using configuration from /etc/pki/tls/openssl.cnf
Enter pass phrase for /etc/pki/CA/private/my-ca.key:
Check that the request matches the signature
Signature ok

#CA中心生成证书
[root@server1 ~]# scp dirsrv.crt 192.168.32.32:/root/.
root@192.168.32.32's password:
dirsrv.crt 100% 3765 3.7KB/s 00:00
[root@server1 ~]# scp /etc/pki/CA/my-ca.crt dirsrv.crt 192.168.32.32:/root/.
root@192.168.32.32's password:
my-ca.crt 100% 1533 1.5KB/s 00:00
#将证书和CA公钥发送给ldap服务器
二、ldap服务器利用redhat-idm-console控制台导入公钥和ca中心公钥，并开启ssl/tls认证
1、导入公钥：选择install，在in this local file对话框中输入ldap服务器公钥
#CA中心公钥导入同上
2、开启ssl/tls认证
3、编辑证书保护密码存放文件，并重启ldap服务器
[root@station2 ~]# vi /etc/dirsrv/slapd-station2/pin.txt
Internal (Software) Token:redhat
#redhat为证书保护密码
[root@station2 ~]# service dirsrv restart
Shutting down dirsrv:
station2... [确定]
Starting dirsrv:
station2... [确定]
#如果证书生成过程中有任何错误，均不能启动dirsrv服务。
[root@station2 ~]# netstat -tunpl|grep 636
tcp 0 0 :::636 :::* LISTEN 10753/ns-slapd
#636端口开启表示ldap已经开启ssl/tls认证
三、客户端开启ssl/tls认证
[root@station2 ~]# vi /etc/openldap/ldap.conf
TLS_CACERT /etc/pki/tls/certs/my-ca.crt
[root@station2 ~]# ldapsearch -x "uid=zhangsan123" -ZZ -LLL

#如果密码指定ca中心公钥，将无法利用-ZZ查询。客户端在从ldap服务器中获取数据时，会提示下载并导入ldap服务器的公钥。
