I am trying to configure detailed error pages for Fim Portal using this article:

How to Configure Detailed Error Pages for the FIM Portal

The problem is that I am using Fim 2010 R2 and I think that the article above is for Fim 2010.

There is (at least) one difference in web.config file. The article says "Enable the ILMError HTTP module" but in my web.config file there is not ILMEerror in httpModules section. Anyway ILMEerror is in modules section and I edited it as the article says.

Unfortunately now when I am connecting to the portal, I get this error message anytime:

Server Error in '/' Application.

So the case is I get that error message above straight after enabling detailed error pages. I think I shouldn't get that error mesage when the portal is working and now the error message is saying that my modifications broke something.

Any comments or ideas or something? Has the configuration changed for Fim 2010 R2?

To enable detailed errors , it says you should "Comment the ILMError HTTP module", can you confirm this is what you have done? You say above that the article says "Enable the ILMError HTTP module" but as far as I can tell, this is if you are disabling detailed error pages, if you are enabling detailed error pages you should comment out this line.

I have followed the guide in R2 and can confirm it works, substituting the ILMError httpModule with the one in modules as you described.

Yes, I have commented it out.

But what you have substituted. Can you give your configuration example?

I didn't substitute it with anything. You could just remove the line temporarily, it would have the same effect as commenting it out:

    <modules runAllManagedModulesForAllRequests="true">
      <remove name="AnonymousIdentification" />
      <remove name="FileAuthorization" />
      <remove name="Profile" />
      <remove name="Session" />
      <remove name="WebDAVModule" />
      <!--<add name="ILMError" preCondition="integratedMode" type="Microsoft.IdentityManagement.WebUI.Controls.ErrorHandlingModule, Microsoft.IdentityManagement.WebUI.Controls, Version=4.1.3479.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />-->

Here is mine. As you can see it is slightly different. Also the version numbers are not the same.

I rolled my VM back to the same version as yours and my web.config still looks the same as my previous clip except for version numbers - not sure what the differences are from in yours.

I think I will take a little break with this thing. I have tried this now for three different environments and allways the same. The portal breaks down.

One more question for you FIM-EN. What Sharepoint version you are using, Foundation?

2010 Foundation in that environment

2010 Foundation in that environment

Ok, I think that is the problem. We are using 2013 Foundation.
