我部署了一个带有Symfony2、FOSUserBundle&Fr3dLdapBundle，但我遇到了以下问题：

MappingException: Class "XXX'Shared'XXXUserBundle'Entity'User" sub class of "FOS'UserBundle'Model'User" is not a valid entity or mapped super class.

这里解释了eAccelerator不兼容，但我没有：

在最近的PHP版本中也尝试过，但问题仍然存在：

PHP 5.5.9-1ubuntu4.5 (cli) (built: Oct 29 2014 11:59:10)

在我的本地主机Windows系统上，使用Xammp 1.7.7（PHP 5.3.8），一切都很好！。

文件用户.php

C： ''examplep''htdocs''Symfony2''src''Xyz''Shared''XYUserBundle''Entity''User.php

注意：Xyz和XYUserBundle表示实际的文本大写。

User.php如下：

<?php

     *
     * @param string $dn Distinguished Name
     */
    public function setDn($dn){
        $this->dn = $dn;
        return $this;
    }
    /**
     * Get Ldap Distinguished Name
     *
     * @return string Distinguished Name
     */
    public function getDn(){
         return $this->dn;
    }

    public function setEmployeeid($employeeid)
    {
        $this->employeeid = $employeeid;
        return $this;        
    }
    public function getEmployeeid(){
        return $this->employeeid;
    }
    public function serialize()
    {
        return serialize(array(
            $this->password,
            $this->salt,

    }
    public function unserialize($serialized)
    {

        ) = unserialize($serialized);
    }
}
