搭建ldap自助修改密码系统--Self Service Password

服务安装：

安装依赖：yum install php70-ldap.x86_64 -y (版本尽可能大于5.3，不然会提示更新php程序) 
                 yum install httpd -y 
  安装Self Service Password：yum install https://ltb-project.org/rpm/6Server/noarch/self-service-password-1.1-1.el6.noarch.rpm

        配置apache: /etc/httpd/conf.d/self-service-password.conf

NameVirtualHost *:80
<VirtualHost *:80>
        ServerName ssp.xinniu.com

        DocumentRoot /usr/share/self-service-password
        DirectoryIndex index.php

        AddDefaultCharset UTF-8
   <Directory "/usr/share/self-service-password">
            AllowOverride None
            Allow from all
 </Directory>
        LogLevel warn
        ErrorLog /var/log/httpd/ssp_error_log
        CustomLog /var/log/httpd/ssp_access_log combined
</VirtualHost>

配置Self Service Password,支持密码修改和邮件重置： vim /usr/share/self-service-password/conf/config.inc.php

这个文件配置项太多了，只写一下改动的

$ldap_url = "ldap://172.xx.xx.xx:389";
$ldap_starttls = false;
$ldap_binddn = "cn=admin,dc=xxxx,dc=com";
$ldap_bindpw = "****";
$ldap_base = "dc=xxxx,dc=com";
$ldap_login_attribute = "uid";
$ldap_fullname_attribute = "cn";
$ldap_filter = "(&(objectClass=person)($ldap_login_attribute={login}))";
$mail_from = "msg_data@xxxx.com";
$mail_from_name = "Self Service Password";
$mail_signature = "";

$notify_on_change = true;
 https://github.com/PHPMailer/PHPMailer)
$mail_sendmailpath = '/usr/sbin/sendmail';
$mail_protocol = 'smtp';
$mail_smtp_debug = 0;
$mail_debug_format = 'html';
$mail_smtp_host = 'localhost';
$mail_smtp_auth = true;
$mail_smtp_user = 'msg_data@xxxxx.com';
$mail_smtp_pass = 'xxxxx;
$mail_smtp_port = 25;

keyphrase = "secret";

配完后
systemctl restart httpd

完成以后，测试系统是否能够使用
打开页面

d
修改密码时不用输入整个dn，直接输入前缀就能够了

测试修改密码时，报错，ldap服务器拒绝咱们修改的密码，通过查看日志加上本身手动验证，发现普通用户没有修改密码的权限。
而后查看ldap官方的手册：http://www.openldap.org/doc/admin24/access-control.html

研究后发现须要修改ldap的条目
文件添加ACL 信息，问题解决，添加命令以下：

ldapmodify -Y EXTERNAL -H ldapi:/// -f updatepass.ldif

updatepass.ldif 文件内容以下：

dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcAccess
olcAccess: to attrs=userPassword
        by self =xw
        by anonymous auth
        by * none

olcAccess: to *
        by self write
        by users read
        by * none

而后试下真的能够修改密码了
