Apache、Trac 和 LDAP - 如何将它们粘合在一起？

Question

我正在尝试设置Trac以通过Debian (Lenny) 服务器上的LDAP 插件授权用户。

LDAP 似乎工作正常，我可以通过以下方式成功查询：

ldapsearch -vLx -h 127.0.0.1 -b "dc=example, dc=com" "(sn=mysurname)"

如果我故意破坏我的 Apache LDAP 地址设置，我会在 /var/log/apache2/error.log 中看到错误

2010-08-27 17:19:38,909 Trac[api] WARNING: LDAP error: No such object (dc=examplefoo,dc=com)

当我访问http://example.com:8022/trac并单击登录按钮时，身份验证窗口会弹出（再次确认 LDAP 正在启动），但是，当我输入正确的用户名/密码时，我只会得到一个 Trac 网络页面：

Trac Error
Authentication information not available. Please refer to the installation documentation.

TracGuide — The Trac User and Administration Guide

日志同样没有帮助（忽略 svn 错误，我知道）：

我的 apache 设置如下。

<VirtualHost example.com:8022>
    ServerName example.com
    ServerAlias example.com

    ProxyRequests Off
    <Proxy *>
      Order deny,allow
      Allow from all
    </Proxy>

    ProxyPreserveHost On
    RewriteEngine On
    RewriteCond %{HTTP:Authorization} ^(.*)
    RewriteRule ^/(.*) http://127.0.0.1:8002/$1 [P]
</VirtualHost>

<Location /trac/login>
   AuthType Basic
   AuthName "Trac"
   AuthBasicProvider ldap
   Order Allow,Deny
   Allow from All
   AuthLDAPURL "ldap://127.0.0.1:389/dc=example,dc=com?uid"
   #should be on if using groups
   AuthzLDAPAuthoritative off
   Require valid-user
   #Require ldap-group cn=tracusers,dc=example,dc=com
</Location>

服务器有许多其他正在开发的服务正在运行，因此端口号是奇数。

我的 trac.ini 是全新安装的，有以下变化：

[ldap]
basedn = dc=example,dc=com
bind_passwd = foo
bind_user = cn=admin,dc=example,dc=com
enable = true
group_rdn = ou=people
host = 127.0.0.1
port = 389
use_tls = false
user_rdn = ou=users

[components]
ldapplugin.* = enabled

为了进行测试，我只需使用以下命令启动 Trac 服务器：

bin/tracd --port 8202 parts/trac

我哪里错了？感觉好像 Apache 配置是错误的，因为 LDAP 似乎确实在工作。

这是启动服务器的正确命令（例如，htpasswd 有它自己的选项）？

从长远来看，运行服务器的最佳方式是什么？世界地理标志？

如果您需要测试“Apache+LDAP+Trac”绑定，则无需运行独立的bin/tracd.

首先尝试在不使用 LdapPlugin 的情况下将 Apache LDAP 身份验证与 Trac 一起使用（它只是添加了管理 LDAP 组的 trac 权限的功能）。您应该在位置配置身份验证/trac/login，Trac 将自动获取经过身份验证的用户名。看这里：TracModWSGI - 配置身份验证这在我的设置中运行良好（Debian Squeeze，Trac 0.12）。因此，只需从 from 中删除所有修改即可trac.ini。

当您获得工作身份验证后，您可以开始配置 LdapPlugin。

恕我直言，WSGI 是在 Apache 上运行 python 应用程序的最佳方式，它快速且简单。
