http baisc 認証で gerrit を設定しようとしていますが、私の httpd 設定は
<VirtualHost *:8081>
    ServerName localhost
    ProxyRequests Off
    ProxyVia Off
    ProxyPreserveHost On
    <Proxy *>
          Order deny,allow
          Allow from all
    </Proxy>
<Location "/login/">
AuthType Basic
AuthName "Gerrit Code Review"
AuthBasicProvider file
AuthUserFile /usr/local/apache/passwd/passwords
Require valid-user
</Location>
ProxyPass / http://localhost:8081/
</VirtualHost>
そして私のgerrit.configは
[gerrit]
        basePath = git
        canonicalWebUrl = http://localhost:8081/
[database]
        type = mysql
        hostname = localhost
        database = reviewdb
        username = gerrit
[auth]
        type = HTTP
[sendemail]
        smtpServer = localhost
        smtpUser = gerrit
[container]
        user = gerrit
        javaHome = /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre
[sshd]
        listenAddress = *:29418
[httpd]
        listenUrl = proxy-http://*:8081/
[cache]
        directory = cache
どこが間違っているのかわかりませんが、http://xxxx:8081へのアクセスは言う
The HTTP server did not provide the username in the Authorization header when it forwarded the request to Gerrit Code Review.
If the HTTP server is Apache HTTPd, check the proxy configuration includes an authorization directive with the proper location, ensuring it ends with '/': 
私の gerrit は inbuild jetty countainer で実行され、私の OS は centos 6.4 です。
どこが間違っていますか。
