更新：这个问题已经解决。我试图验证各种管理员帐户，这些帐户显然位于一个单独的数据库中，而不是该服务与之交谈的用户帐户。我使用了在 CISCO 中创建的通用用户帐户，并且 Web 服务调用效果很好！
我还要感谢@Yahia 对运行 Fiddler 的建议！
几天来，我一直在阅读CICCO UCP Web Service 文档。我可以使用正确的凭据与盒子上的一个 Web 服务通信，并且一切正常；但是，使用UCP Service时，出现错误... SoapUI 似乎理解 WSDL 文件，并且我能够向端点发送请求，但出现身份验证错误，如下所示。
我使用相同的用户名和密码登录 ACS 门户，因此帐户不会过期。我几乎迷失了这一点，并受制于 CICSO 技术支持。 欢迎任何和所有想法！
