PHPBB结合CAS在linux下配置时候出现问题，急急急。。

在linux下结合CAS时候出现问题，安装好mysql php apache tomcat ssl环境之后
按照在PHPBB中加入CASClient 的代码配置了下
in function.php

Add require($phpbb_root_path . 'includes/CAS.' . $phpEx);

Find (isset($_POST['login']))

Replace it with:

if(!$admin && CAS_ENABLE){ 

// initialize phpCAS 

phpCAS::client(CAS_VERSION_2_0, CAS_SERVER_HOSTNAME, CAS_SERVER_PORT, CAS_SERVER_APP_NAME); 

phpCAS::setNoCasServerValidation(); 

// force CAS authentication 

phpCAS::forceAuthentication(); 

} 

if (isset($_POST['login']) || (!$admin && CAS_ENABLE) )

Find $result = $auth->login($username, $password, $autologin, $viewonline, $admin);

Add the following code before it:

if(!$admin && CAS_ENABLE){ 

$username = phpCAS::getUser(); 

$password = ''; 

}

在In Auth.php

Add the following function:

function login_cas($username){ 

global $db; 

$sql = 'SELECT user_id, username, user_password, user_passchg, user_pass_convert, user_email, user_type, user_login_attempts FROM ' . USERS_TABLE 

. " WHERE username_clean = '" . $username . "'"; 

$result = $db->sql_query($sql); 

$row = $db->sql_fetchrow($result); 

$db->sql_freeresult($result); 



if (!$row) { 

return array( 

'status' => LOGIN_ERROR_USERNAME, 

'error_msg' => 'LOGIN_ERROR_USERNAME', 

'user_row' => array('user_id' => ANONYMOUS), 

); 

} 



if ($row['user_type'] == USER_INACTIVE || $row['user_type'] == USER_IGNORE) { 

return array( 

'status' => LOGIN_ERROR_ACTIVE, 

'error_msg' => 'ACTIVE_ERROR', 

'user_row' => $row, 

); 

} 



// Successful login... set user_login_attempts to zero... 

return array( 

'status' => LOGIN_SUCCESS, 

'error_msg' => false, 

'user_row' => $row, 

); 

}

Find $login = $method($username, $password);

Replace it with:

if(!$admin && CAS_ENABLE)    

$login = $this->login_cas($username);    

else    

$login = $method($username, $password);

In constants.php

Add the following constant value:

define('CAS_ENABLE', true); 

define('CAS_SERVER_HOSTNAME', 'localhost'); 

define('CAS_SERVER_PORT', 8443); 

define('CAS_SERVER_APP_NAME', 'cas');

在phpBB3论坛里面点击登录跳到CAS server 的公共登录界面，输入用户名密码登录
看见url上已经出现获得了ticket，但是页面显示出错误如下：

[phpBB Debug] PHP Notice: in file /includes/CAS/client.php on line 529: session_destroy() [function.session-destroy]: Trying to destroy uninitialized session

CAS Authentication failed!
