When I try to create a channel, I got an error like below:
implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy requires 1 of the 'Writers' sub-policies to be satisfied: permission denied
As the error message said, it seems like that I'm using wrong identity to sign the transaction to create a channel. However, I cannot find any mistake about the channel configuration or the identity registration & enrollment.
My channel config for the organization is:
Organizations:
- &BPLOrg
Name: BPLMSP
ID: BPLMSP
MSPDir: artifacts/crypto/org-msp
Policies:
Readers:
Type: Signature
Rule: "OR('BPLMSP.admin', 'BPLMSP.peer', 'BPLMSP.client')"
Writers:
Type: Signature
Rule: "OR('BPLMSP.admin', 'BPLMSP.client')"
Admins:
Type: Signature
Rule: "OR('BPLMSP.admin')"
So, according to the config, admin type identity can sign the transaction to create the channel.
My admin type identity is already registered and enrolled like below:
fabric-ca-client register -d --id.name $ADMIN_ID --id.secret $ADMIN_PW --id.type admin -u https://$CA_ADMIN_ID:$CA_ADMIN_PW@$CA_NODE:7054
fabric-ca-client enroll -d --csr.names $CSR -u https://$ADMIN_ID:$ADMIN_PW@$CA_NODE:7054
Registration & Enrollment were processed well with the argument --id.type admin and, to sign the transaction to create a channel, I'm using the key that I got from this enrollment.
Where can I start to invest this error? Any kind of ideas will be very helpful. Thanks!

At this point, I'm curious that how I can get the admin identity. My policy is 'MSP.admin' and I'm using the identity, which is registered with the argument --id.type admin.
Writers policyThe admin was actually correctly set up, or else the orderer would complain about the Admins policy not being satisfied. What has happened is that the orderer has accepted the request and created the genesis block for the channel. It then proceeds to set up a handler to broadcast future blocks for that channel, and in doing so it verifies that its certificate satisfies the /Channel/Writers policy, which is required to call the Broadcast API.
The mentioned policy is by default an of type ImplicitMeta, which means it should be satisfied via /Channel/Orderer/<ORG NAME>/Writers. Because the error message states that only 1 sub-policy needs to be satisfied (i.e. ANY Writers), it means your orderer's certificate does not meet up to its own organization's Writers policy. You need to add the OU type for an orderer to the rule, or set it to member to allow any certificate in the org to act as writer:
Writers:
Type: Signature
Rule: "OR('<ORG NAME>.admin', '<ORG NAME>.client', '<ORG NAME>.orderer')"
Admins:
Type: Signature
Rule: "OR('BPLMSP.member')"
This will allow you to create a certificate within the BPLMSP org whenever, of whatever type, and use it for administrative purposes such as creating a channel. Fabric will skip checking the cert type (organizational unit, OU) and only check it is signed by the org's CA. Be aware that this loosens the security within your organization, as any (lost) certificate will have administrative rights.
client, peer or orderer with Fabric CAadmincerts/ of the BPLMSP org's MSPMSPDir for BPLOrg points to the BPLMSP org's MSPAdmins policy for BPLOrg to rule "OR('BPLMSP.admin')"If you want to join a peer to a channel and sign the request with the created certificate, then you will have to add the cert into the admincerts/ folder for that peer's local MSP. The peer reads this directory on boot, so you will have to restart it if you've made changes to the directory while it was running.
If you want to add an additional admin certificate while the network is already configured, you will have to perform a genesis block update, which should include the new certificate.
v1.4.3This option allows you to register certificates as admins without having to add it to the genesis block, and without loosening security by having all types of certificates as admins.
This only works if:
OrganizationalUnitIdentifier is set for AdminOUIdentifier for the orgYou would then proceed by enrolling a new identity and setting the type (OU) to match the OrganizationalUnitIdentifier. The certificate does not need to be added to the OSN's genesis block, as it will be identified as an admin based on the type (OU). See Hyperledger Fabric's doc for Identity Classification.
To create a channel, the ChannelCreationPolicy must be fulfilled. This defaults to ANY /Channel/Application/Admins. The policy cannot be set using configtxgen, the only way to modify it is by making a change to the genesis block. See FAB-13192.
The rule type <MSP ID>.admin is not the same as identity/certificate type (OU) admin. The rule type refers to signatures that have administrative permissions, however these signatures can come from certificates of any type (OU).
You do not create an admin by:
admin type (OU) pre v1.4.3hf.Admin=true as the Amazon Managed Blockchain doc claims (this will fail as it is not a valid attribute)admin=true:ecert as in the Fabric CA docs (Fabric only looks at attributes beginning with hf., so this has no effect other than adding confusion).You can register a CA identity with any type, however valid admin certificates must be of (OU) type peer, orderer, client, or as OrganizationalUnitIdentifier is set for AdminOUIdentifier. Don't use the fabric-ca-client identity add command, as it will register an identity of type user. I can't say I know what the purpose of this type is.
