Non-administrators fail to access the FIM portal. Adding the user to the Administrators set allows access.
The typical error message displayed is “unable to process your request.” Configuring detailed error messages in the portal garnered an “Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index” error.
Modifications made to the FIM portal home page removed all the elements from the standard users’ third pane view. At least one home page resource must exist in that pane.
In this case both the “About Forefront Identity Manager” and “Help” resources were removed.
Just add back at least one of the resources.
With one or more resources in the BasicUI standard users may access the FIM portal.
To enable the detailed error messages please see the “How to Configure Detailed Error Pages for the FIM Portal” wiki entry.
