MIM portal error "Unable to process your request" after applying SharePoint Server updates

Applies to: Microsoft Identity Manager 2016 SP2Microsoft Identity Manager 2016 SP1Microsoft Forefront Identity Manager 2010 R2 Service Pack 1

Cause


The security level of SharePoint ghosted pages was enhanced by forbidding server-side scripts and unsafe controls. Because MIM portal uses server-side scripts, its pages are blocked from rendering.

Workaround


To work around this issue until the next MIM hotfix is released, add a new PageParserPath element that has a VirtualPath attribute to the Web.config file under the configuration/SharePoint/SafeMode/PageParserPaths element, as follows:

     <SafeMode MaxControls="200" CallStack="false" DirectFileDependencies="10" TotalFileDependencies="250" AllowPageLevelTrace="false">
          <PageParserPaths>
               <PageParserPath VirtualPath="/identitymanagement/*" CompilationMode="Always" AllowServerSideScript="true" IncludeSubFolders="True"/>
          </PageParserPaths>
     </SafeMode>
