通过web修改svn用户密码

使用方法:

1. 将文件changePasswd.cgi和changePasswd.ini 放到apche安装目录下的cgi-bin下（cgi-bin的目录可以通过/etc/httpd/conf/httpd.conf查找）
2. 确认changePasswd.cgi 程序第1行 ，prel工具的位置   （eg：#!/usr/bin/perl -w）
3. 修改changePasswd.cgi 中$inifile的值为changePasswd.cgi的路径（eg:/var/www/cgi-bin/changePasswd.ini）
4. 配置文件 changePasswd.ini ,authuserfile= 密码存放路径 （eg:/var/www/svn/passwdfile）
5. 配置文件 changePasswd.ini ,logfile= 操作日志存放路径 （eg:/var/www/svn/changPasswd.log）
6. chmod -R 755 cgi-bin目录(eg: /var/www/cgi-bin)
