Ask your authentication provider administrator if it supports an Apache Tomcat servlet filter . If not, then it is expected that the authentication provider has a isapi filter that can be used with IIS. We will have to use the SBM proxy in IIS.
Please gather any applicable information from the list below and contact Dimensions Support for help with this error message. What you need to troubleshoot:
If you are having problems using SBM web-services and you have setup SSO to use External Filters, then it is possible there is more manual configuration required. If you have External Filters defined in SSO and are having problems with Web Services, then contact Support
