IBM AS400链接服务器到SQL Server 2012

Question

我设置了链接服务器，效果很好。我用了很多年了。最近我们需要访问不同的库，包括我们目前可以访问的库。我们的IT部门给了我们一个新的用户名和密码。我使用新的用户名和密码设置了一个新的链接服务器（从工作中编写脚本）。我收到以下错误。

Cannot initialize the data source object of OLE DB provider "DB2OLEDB" for linked server "400_TEST".
OLE DB provider "DB2OLEDB" for linked server "400_TEST" returned message "The user does not have the authority to access the host resource. Check your authentication credentials or contact your system administrator.". (Microsoft SQL Server, Error: 7303)

问题：因为我们的另一个工作正常，它必须在400方面具有权限。他们声明InitCat = ####和QGPL都有访问权限。什么是用于DB2的Microsoft OLE DB提供程序（DB2OLEDB）的主机资源＆＃39;正试图联系？是否有隐藏的东西我需要他们授予访问权限？
