Allow me to illustrate this using an example scenario, where a PI End User wants a certificate without going through their sponsoring LIR:
1: The PI End User logs in with their RIPE NCC Access account on
ripe.net (after creating one)
2: They go to a webpage with a form where they enter the prefix(es) they would like a resource certificate for
3: The background system checks if these prefixes:
a) are PI End User resources
b) have the status "End User Documents Approved", meaning that a RIPE-452 contract was submitted and verified
4: The PI End User must enter the RIPE Database MNTNER password/key(s) for the inetnum objects of the resources, to prove they have authoritative control over them
5: If this is successful, the RIPE NCC Access credentials, resources and ROA management interface are associated with each other, allowing them to use the system
It is up to the Community and membership to decide if this would be an acceptable workflow or if additional steps or checks would need to be added.
You should keep in mind that at all times, the sponsoring LIR is the only point of contact the RIPE NCC has, and according to the signed contract they are held responsible for the resources and PI End User relationship.
Cheers,
