MKCOL 405 и LOCK 500 при git push (ошибка: невозможно заблокировать существующую информацию / ссылки)

У меня проблемы с настройкой сервера Git с apache.

Вот мой gitrepo.conf:

DavLockDB "opt/local/apache2/var/DavLock"

<Directory /opt/local/apache2/htdocs/repo>
  DAV On
  Deny from all
  AuthType Basic
  AuthName "Git repositories"
  AuthUserFile /etc/apache2/other/htpasswd
  AuthGroupFile /etc/apache2/other/htgroup-git
</Directory>

<Directory /opt/local/apache2/htdocs/repo/myproject.git>
  Allow from all
  Order allow,deny
  <Limit GET>
    Require group myproject-reader
  </Limit>
  <Limit GET PUT POST DELETE PROPFIND PROPPATCH MKCOL COPY MOVE LOCK UNLOCK>
    Require group myproject-writer
  </Limit>
</Directory>

Когда я git push к http://admin@localhost/repo/myproject.git, Я получаю это:

error: cannot lock existing info/refs
fatal: git-http-push failed

Вот отрывок из моего журнала access_log:

::1 - - [28/Jul/2012:19:05:52 +0100] "GET /repo/myproject.git/info/refs?service=git-receive-pack HTTP/1.1" 401 401

::1 - admin [28/Jul/2012:19:05:57 +0100] "LOCK /repo/myproject.git/info/refs HTTP/1.1" 500 535

Кажется, я получаю ошибку 405 с MKCOL и ошибку 500 с LOCK.

И вот мой error_log:

[Sat Jul 28 19:05:52 2012] [error] [client ::1] user admin: authentication failure for "/repo/myproject.git/info/refs": Password Mismatch
[Sat Jul 28 19:05:57 2012] [error] [client ::1] Could not LOCK /repo/myproject.git/info/refs due to a failed precondition (e.g. other locks).  [500, #0]
[Sat Jul 28 19:05:57 2012] [error] [client ::1] The locks could not be queried for verification against a possible "If:" header.  [500, #0]
[Sat Jul 28 19:05:57 2012] [error] [client ::1] Could not open the lock database.  [500, #400]
[Sat Jul 28 19:05:57 2012] [error] [client ::1] (2)No such file or directory: Could not open property database.  [500, #1]

И я я ввод правильного пароля в виде команд вроде git remote show origin который запрашивает пароль, принимает его нормально.

Любые идеи?
