the identity certificate does not contain an Organizational

Error message

the identity certificate does not contain an Organizational Unit (OU)

What it means

validateIdentityOUsV1 guard: OU identifier enforcement is active (msp.ouIdentifiers is non-empty) but the identity certificate contains no Organizational Unit at all, so it cannot match any configured OU-to-certifier mapping.

Solutions

1. Reissue the certificate with an OU matching a configured OrganizationalUnitIdentifier
2. Add the certificate's OU to the MSP config's OU identifiers
3. Disable OU enforcement if the channel does not require it
