Dear DB-WG, RIPE, The chairs unanimously concluded there is enough support in the group to implement the 'personalised authorisation' proposal as described below. No objections have been raised against the concept of personalised authorisation itself, although one different idea was raised on how to structure it (roles versus maintainers). Based on feedback on the mailinglist and in the last DB-WG session at RIPE70, it is our assessment that the below proposal is an excellent starting point as it stands. Note that we can always revisit/improve on the implementation at a later point. I ask RIPE NCC to create a proof of concept in the RC environment. The moment this POC is available we will start banging on it and possibly suggest futher improvements. Kind regards, Job, Piotr, Nigel On Wed, Apr 08, 2015 at 09:07:58AM +0100, Tim Bruijnzeels wrote: > The RIPE NCC has discussed the concept of personalised authorisation > on various occasions, most recently at the DB WG session at RIPE 69. > Following discussions and input from the working group we would now > like to propose the following additions to the RIPE Database: > > = Extend the person object template with "auth:" as an optional, > multiple attribute, with all current authentication methods. > = Extend the mntner object "auth:" attribute with a new method that > allows a reference to a person object that has at least one "auth:" > attribute. > > There is no requirement to use these extensions, but users that choose > to do so can benefit from the following advantages: > > = Currently it is is not always clear who uses the credentials in each > "auth:" attribute on a mntner.
