Is there a good technique (perhaps a PowerShell script?) to find where portal attributes are referenced/in use?
I'm trying to delete an obsolete attribute from the portal which was previously used in a few places, but I'm getting a "processing error" when I go to unbind the attribute from the user resource - presumably meaning it's in use or referenced somewhere.
I've hunted through sets, filters permissions, workflows and cleared all values on users etc., etc. but cannot find where this thing is referenced/in use.
Any tips or tricks would be hugely appreciated.
