etch升级后svn的问题couldn't check user. No user file?

etch

今天升级后，apache更新到了2.2，svn更新到了1.4，然后apache就不能启动，显示
Invalid command 'AuthUserFile', perhaps misspelled or defined by a module
not included in the server configuration

折腾了好久，后来我重装了svn和apache2
google了一下，运行"a2enmod authn_file"命令加载authn_file模块，然后apache可以启动了，svn也可以访问，但是不能提交！

在eclipse客户端出现错误
commit -m "" E:/workspace/testsvn/trunk/svntest/src/test/Test.java
    RA layer request failed
svn: Commit failed (details follow):
