之前几天在Linux Server上重新创建了一个新的环境，用自己的帐号check out了新的代码，但是发现每次update的时候需要输入密码，很繁。Google了一下，其中一个解决方法是在/home/<user>/.subversion/目录下的config文件找到一下配置：
### Section for authentication and authorization customizations.
[auth]
### Set store-passwords to 'no' to avoid storing passwords in the
### auth/ area of your config directory. It defaults to 'yes'.
### Note that this option only prevents saving of *new* passwords;
### it doesn't invalidate existing passwords. (To do that, remove
### the cache files by hand as described in the Subversion book.)
# store-passwords = no
将“store-passwords = no” 注释掉或将其值设置成true。
