But I've not encountered any problems with it in several years, and changing to it is as simple as replacing your current config with something like this. (You might adjust the caching time, or the name of the signing cert file depending on where you put it and what you call it. And unless you have rules in your filter file for release to "any metadata retrieved from InCommon", you won't need the entity attribute added. But it also won't hurt anything.)
