在http://192.168.0.20/_vti_bin/cmissoapwsdl.aspx作为Web服务登录到我启用CMIS的SharePoint 2013 Standard时，CMIS Workbench说：
ClientHelper: CmisConnectionException: Cannot initalize Web Services service object
这是端点的响应（pastebin，因为StackOverflow限制为30k个字符），在我看来还可以，那么问题出在哪里呢？

可能存在身份验证问题。尝试使用web浏览器将WSDL下载到本地磁盘，然后在工作台中使用文件：//URL引用它。
如果有效，请检查SharePoint端的身份验证配置。OpenCMIS无法处理受保护的WSDL。
