    Hi Guys,

    I'm trying to create a new root CA with the following DN:

    CN=KDM Signer CA,OU=Development,O=PRIMA Cinema,dnQualifier=IpjMnpUKimBnwPx6zNr3FbQn8Kw=

    Where dnQualifier is the sha-1 thumbprint of the new CA's public key encoded to base64. When the CA is created the "dnQualifier" field is stripped from the DN (with no error message) resulting in just:

    CN=KDM Signer CA,OU=Development,O=PRIMA Cinema

    This is not what I want...

    Including the dnQualifier field in the DN is a hard requirement for creating D-Cinema spec'd (DCI) certificates and must not be ommitted. Can someone tell me how to keep the dnQualifier included as part of the CA's DN?

    Thanks in advance for your help!

    Blessings,
    Brian

    I used the following:
    CN=CAWithDNQualifier,O=foo,DN=IpjMnpUKimBnwPx6zNr3FbQn8Kw\=

    It produces a certificate with the following openssl dump:

    openssl x509 -in ~/tmp/CAWithDNQualifier.cacert.pem -text
    Certificate:
    Data:
    Version: 3 (0x2)
    Serial Number: 133999823631200639 (0x1dc10212f80b17f)
    Signature Algorithm: sha256WithRSAEncryption
    Issuer: dnQualifier=IpjMnpUKimBnwPx6zNr3FbQn8Kw=, CN=CAWithDNQualifier, O=foo
