此方法经centos 5.3/5.4 ，apache+php 验证可用。
增加虚拟目录
vi /etc/httpd/conf/httpd.conf 文件最后添加
Alias /svnadmin "/var/www/html/svnadmin/"
<Directory "/var/www/html/svnadmin">
Require valid-user
AuthType Basic
AuthName "SVN user password modify"
AuthUserFile /etc/httpd/svn/htpasswds
</Directory>
我的svn帐号信息存在/etc/httpd/svn/htpasswds ,apache 能够读写此目录
vi /var/www/html/svnadmin/index.php
将以下内容放插入index.php
<?
/*
Alias /svnmodify "/var/www/html/svnadmin/"
<Directory "/var/www/html/svnadmin/">
Require valid-user
AuthType Basic
AuthName "Subversion Tools"
AuthUserFile /etc/httpd/svn/htpasswds
</Directory>
*/
?>
