Alternative for rlm_attr_filter for filtering vsa

Hi list, In the past, I used rlm_attr_filter to only allow listed attributes to be sent to a home server. This worked for both RFC and VSA attributes. Based on the changelog, the functionality of rlm_attr_filter changed as of version 3.0.2: FreeRADIUS 3.0.2 Fri 21 Mar 2014 08:30:00 EDT urgency=medium Feature improvements * Prevent vendor attributes and RFC space attributes from clashing in rlm_attr_filter. If I understand correctly, it is no longer possible to match a specific VSA. And I can't seem to figure out how to do that with unlang or any other module. So is there any way to remove all attributes except for a list of allowed attributes (both RFC and VSA)? Kind regards, Thor
