Things would be much more simple if we proceed with approaches such as what is proposed in https://datatracker.ietf.org/doc/draft-boucadair-veloce-yang/ With the current practices, new identities can be added in a future revision of the module or by deviation. Defining arbitrary identities for exhaustiveness is not better either because there is currently no way in YANG/RC/NC that a subset of identities are not implemented. This is an issue that is queued for yang-next, e.g., https://github.com/netmod-wg/yang-next/issues/107. I can point to other relevant issues.

This is indeed a separate aspect that is covered by the para next the one quoted above. This is related the RBAC guards used out there. The client identity is used to tag which piece of data/operation a client is entitled to. We don't repeat this considerations here as this is covered by rfc8341#section-3.4.5. After thinking about this, I don't think it is harmful to remind this. I made this change: OLD: The Network Configuration Access Control Model (NACM) [RFC8341] provides the means to restrict access for particular NETCONF or RESTCONF users to a preconfigured subset of all available NETCONF or RESTCONF protocol operations and content. NEW: Servers MUST verify that requesting clients are entitled to access and manipulate a given bearer or AC. For example, a given customer must have access only to its bearers/ACs and be discarded access to bearers/ACs of other customers. The Network Configuration Access Control Model (NACM) [RFC8341] provides the means to restrict access for particular NETCONF or RESTCONF users to a preconfigured subset of all available NETCONF or RESTCONF protocol operations and content. ____________________________________________________________________________ ________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
