x.509 certificate UID field #fabric-ca #fabric-ca-client



we are currently trying to figure out how to (if at all possible) specify the UID field (subjectUniqueID in https://tools.ietf.org/html/rfc5280#section-4.1) during registration/enrollment with Fabric CA.
More specifically, we want to do something like this:
fabric-ca-client ... --csr.names C=US,ST=North Carolina,L=,O=Hyperledger,UID=SomeUID
Is this currently (v1.4.9) possible? Or can we specify a CSR file (maybe generated with OpenSSL and containing UID) for registration/enrollment? If not, how would you recommend we could achieve this?
