Hyperledger Fabric enroll & register admin not working

Question

I'm trying to enroll & register an admin to perform peer operations. This is the bash code:

#!/bin/bash
user="$1"
pass="$2"
org="$3"
type="$4"
tlscerts="/chainset/hyperledger-config/crypto-config/ordererOrganizations/default.svc.cluster.local/msp/tlscacerts/ca-root-7054.pem"

fabric-ca-client enroll -u http://admin:adminpw@ca-root:7054

fabric-ca-client register --id.name ${user} --id.secret ${pass} --id.type ${type} --id.affiliation ${org} --id.attrs 'hf.Revoker=true,admin=true:ecert' -u http://ca-root:7054 --tls.certfiles ${tlscerts}

export FABRIC_CA_CLIENT_HOME=/chainset/hyperledger-config/crypto-config/peerOrganizations/${org}/users/${user}@${org}/
fabric-ca-client enroll -u http://${user}:${pass}@ca-root:7054 --id.affiliation ${org} --tls.certfiles ${tlscerts} 

mv /chainset/hyperledger-config/crypto-config/peerOrganizations/${org}/users/${user}@${org}/msp/signcerts/cert.pem /chainset/hyperledger-config/crypto-config/peerOrganizations/${org}/users/${user}@${org}/msp/signcerts/${user}@${org}-cert.pem
mkdir /chainset/hyperledger-config/crypto-config/peerOrganizations/${org}/users/${user}@${org}/msp/admincerts/
cp /chainset/hyperledger-config/crypto-config/peerOrganizations/${org}/users/${user}@${org}/msp/signcerts/* /chainset/hyperledger-config/crypto-config/peerOrganizations/${org}/users/${user}@${org}/msp/admincerts/

When I try to create a new channel I get this error:

Description: error validating channel creation transaction for new channel 'newchannelf', could not successfully apply update to template configuration: error authorizing update: error validating DeltaSet: policy for [Group]  /Channel/Application not satisfied: implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy requires 1 of the 'Admins' sub-policies to be satisfied

This is my configtx.yml configuration. I don't know if it is a problem with the policies in this configuration file or if I'm not registering & enrolling the user correctly.

Answer 1

This is what is happening:

You created a system channel (which is the orderer genesis block) by creating the MAIN consortium. Now the system channel was created with the peer organization MSPs at that moment. Followed by this, after the network was up, you went into org1/users and created an admin identity. You update local MSP of peer but the already existing system channel was never updated.

Possible solutions:

1. Update the admin credentials within org1/users before the network is set up.
2. Update the system channel configuration with the admin2 credentials post deployment by creating a channel update transaction.
3. Enable NodeOUs so that any admin identity generated dynamically post the network deployment can perform admin related transactions.
