将 Squid 与 Active Directory 集成

将 Squid 与 Active Directory 集成

我正在尝试将 Squid 集成为 Active Directory 中用户的 Web 代理。我已按照 Squid 网站中的教程进行操作这里。当我运行命令时：

msktutil -c -b "CN=Administrator" -s HTTP/proxy.example.com -k /etc/squid3/PROXY.keytab \
--computer-name SQUIDPROXY-K --upn HTTP/proxy.example.com --server acdc.example.com --enctypes 28 --verbose

我收到错误：

SASL/GSSAPI 身份验证已开始  
错误：ldap_sasl_interactive_bind_s 失败（本地错误）  
        附加信息：SASL(-1)：通用故障：GSSAPI 错误：未指定的 GSS 故障。次要代码可能提供更多信息（Kerberos 数据库中未找到服务器）  
错误：ldap_connect 失败。

文件/etc/squid3/PROXY.tab也没有被填充。我搜索了整个互联网，但没有找到有关此问题的任何信息。

这是我的配置文件：

/etc/krb5.conf

[logging]
default = FILE
kdc = FILE
admin_server = FILE

[libdefaults]
    default_realm = DOMAIN.COM
    dns_lookup_kdc = no
    dns_lookup_realm = no
    ticket_lifetime = 24h
    default_keytab_name = /etc/squid3/PROXY.keytab



; for Windows 2008 with AES
;      default_tgs_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5
;      default_tkt_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5
;      permitted_enctypes = aes256-cts-hmac-sha1-96 rc4-hmac des-cbc-crc des-cbc-md5



[realms]
DOMAIN.COM = {
   default_domain = domain.com
   kdc = acdc.domain.com
   kdc = acdc2.domain.com
   admin_server = acdc.domain.com
}

[domain_realm]
        .domain.com = DOMAIN.COM
        domain.com = DOMAIN.COM

这是错误输出：

--> Is your kerberos ticket expired? You might try re-"kinit"ing.
--> Is DNS configured correctly? You might try options "--server" and "--no-reverse-lookups".

还有另一种方法可以让 Squid 与 AD 集成 - 不将机器加入 AD，而是将 AD 用户映射到 Squid 的主体名称。这似乎更简单 - 请参阅http://docs.diladele.com/administrator_guide_4_3/active_directory/install_prerequisites_for_kerberos_authentication.html#prepare-a-user-in-example-lan-domain-to-be-used-by-squid-for-kerberos-authentication
