[ncc-services-wg] How to change maintainer pw without RIPE Account?

Hello, i did work as consultant for various RIPE members during the last 20 years and got hit by the "Maintainer Objects Removed on 13 July 2015" campaign. I need to change my maintainer object but cant because i dont have an ripe account but did use the ones of my clients. How can i proceed? best regards, Arnd
