svn無法登入 - Linux

我的svn repository是建在/svn/repos
但執行網頁登入http://localhost/svn/repos
輸入帳號密碼卻一直說我的密碼錯誤無法登入

去看/etc/httpd/logs/error_log有錯誤訊息
無法存取我的passwd檔案及id沒configure

以下是我建立的步驟

mkdir /svn
mkdir /svn/repos
mkdir /svn/users
mkdir /svn/permissions

chown -R apache.apache /svn

svnadmin create /svn/repos

vi /svn/repos/conf/svnserve.conf
anon-access = none
auth-access = write
password-db = /svn/users/svnpass
realm = My SVN Repository

vi /svn/users/svnpass
[Users]
tai=1234

vi /etc/httpd/conf.d/subversion.conf
<Location /svn/repos>
DAV svn
SVNParentPath /svn/repos
#
# # Limit write permission to list of valid users.
# <LimitExcept GET PROPFIND OPTIONS REPORT>
# # Require SSL connection for password protection.
# # SSLRequireSSL
#
AuthType Basic
AuthName "Authorization Realm"
AuthUserFile /svn/users/svnpass
AuthzSVNAccessFile /svn/permissions/svnauthz.conf
Require valid-user
# </LimitExcept>
</Location>

htpasswd -c /svn/users/svnpass tai

vi /svn/permissions/svnauthz.conf
[/]
tai=rw

service httpd restart

有試著把passwdfile路徑改到/svn/repos/conf/passwd但還是一樣
不知道有沒有人碰到一樣的問題，可以回答一下，謝謝
