LDAP适用于PHP CLI,但不适用于apache

我正在尝试从Fedora框中针对Windows 2008 Server对LDAP进行身份验证.

以下代码从命令行工作(打印"成功"):

if($ldap = ldap_connect('10.0.0.101'))
{
  ldap_set_option($ldap, LDAP_OPT_PROTOCOL_VERSION, 3);
  $bind = ldap_bind($ldap,'administrator@domain.tld','XXXXXXX');
  print ldap_error($ldap);
}

...通过Apache/mod_php拉相同的文件打印"无法联系LDAP服务器"

我已经看过很多关于这类问题的报告,但没有关于如何解决它的有用信息.

我刚刚在centos6上与这个问题进行了长时间的斗争.php.ini差异似乎是一个值得检查的好地方,但它没有给我答案.事实证明这与SELinux有关.

$ getsebool -a | grep httpd
allow_httpd_anon_write --> off
allow_httpd_mod_auth_ntlm_winbind --> off
allow_httpd_mod_auth_pam --> off
allow_httpd_sys_script_anon_write --> off
httpd_builtin_scripting --> on
httpd_can_check_spam --> off
httpd_can_network_connect --> off
httpd_can_network_connect_cobbler --> off
httpd_can_network_connect_db --> on
httpd_can_network_memcache --> on
httpd_can_network_relay --> off
httpd_can_sendmail --> off
httpd_dbus_avahi --> on
httpd_enable_cgi --> on
httpd_enable_ftp_server --> off
httpd_enable_homedirs --> off
httpd_execmem --> off
httpd_manage_ipa --> off
httpd_read_user_content --> off
httpd_run_stickshift --> off
httpd_setrlimit --> off
httpd_ssi_exec --> off
httpd_tmp_exec --> off
httpd_tty_comm --> on
httpd_unified --> on
httpd_use_cifs --> off
httpd_use_gpg --> off
httpd_use_nfs --> off
httpd_use_openstack --> off
httpd_verify_dns --> off

你会注意到,在我的情况下,httpd_can_network_connect被设置为关闭.这是SELinux中的布尔值,可以使用以下命令进行调整.

$ setsebool -P httpd_can_network_connect on

您可以在http://wiki.centos.org/TipsAndTricks/SelinuxBooleans上阅读更多相关内容,其中明确使用apache和ldap的示例作为示例.希望能帮助到你!
