【问题描述】:
我正在尝试使用系统上创建的本地用户连接到 IBM MQ 队列管理器。
我使用的是 Win server 2008 R2,IBM MQ 客户端和服务器版本是 8.0.0.6
为了以本地用户身份运行代码,我实现了模拟。现在,当我冒充用户并尝试连接时,出现以下连接错误。当我以其他用户(本地用户)身份运行 Visual Studio 时,它可以工作,但在我使用模拟时却不行。
下面是轨迹:

文件
C:\Program Files\IBM\WebSphere MQ\bin\mqe.dll是否存在?被模拟的用户是否有权访问该文件?您想模拟运行它的原因是什么?以这种方式使用模拟将表明队列管理器上的 SVRCONN 通道不安全,并且只是接受您在服务器上模拟的用户标识为有效。使用 MQv8,您可以将用户名和密码发送到队列管理器,如果设置,它将验证并使用该 ID 来确定服务器上的 MQ 访问,不需要模拟并且安全性更好,因为您正在验证。 -

C:\Program Files\IBM\WebSphere MQ\bin\mqe.dll是否存在?被模拟的用户是否有权访问该文件? -
是的,它确实存在,并且模拟用户可以访问它。当 Visual Studio 作为不同的用户(我正在模拟的本地用户)运行时,它就像黄油一样工作。当我冒充它运行它时,同样不起作用。我正在使用 MQ 版本 8.0.0.6 。 MQ 服务器中的用户没有设置密码,它只有用户名。我不能只设置用户名并连接到 MQueueManager。我希望你的意思是在哈希表属性中设置用户 ID 属性和密码。请告诉我是否可以仅使用用户名来完成?
-
正如我所说,它作为您模拟的用户工作这一事实对安全性来说是一个不好的迹象,因为它表明队列管理器只是接受断言的用户 ID。使用 IBM MQ Classes for Java 或 JMS,断言您想要的任何 id 都是微不足道的。使用 .NET 等其他 API,您需要在该名称的用户下运行以声明 id,但如果您有权创建本地用户,这也是微不足道的。实际上通过
CONNAUTH验证ID 和密码并使用ADOPTCTX(YES)意味着您现在还需要密码才能连接。 -
如果您想继续排除模拟不存在的原因,我建议您在服务器上启用 MQ 跟踪。另一种选择是,基于它正在寻找
mqe.dll的事实,它表明它已成功调用amqmdnet.dll,但在非托管模式下运行,这意味着它需要其他非.NET dll 作为客户端安装的一部分。如果您在托管模式下运行它,则不需要任何 dll,除了amqmdnet.dll。
