Hi,

has anybody in this list experiences with OpenCA as a Sub-CA in respect of
SCEP? We already have an established PKI and I want to use the OpenCA as a
Sub-CA for PIX firewalls within our PKI.

So I have installed OpenCA-0.9.2-RC3 as a Sub-CA and imported a certificate
issued by our root CA. Then I signed a certificate for myself as CA admin
and I also use this cert for the scep interface.

The config on the PIX are as follows:

ca identity test-ca 10.20.0.4:/cgi-bin/scep/scep
ca configure test-ca ra 1 20 crloptional
ca authenticate test-ca

So I got following error messages: (debug crypto ca)

CRYPTO_PKI: WARNING: A certificate chain could not be constructed while
selecting certificate status

CRYPTO_PKI: Error:  Code 0x0000 while selecting self signed certificate

CRYPTO_PKI: WARNING: Certificate, private key or CRL was not found while
verifying cert in message by issuer self-signed cert

CRYPTO_PKI: WARNING: A certificate chain could not be constructed while
selecting certificate status

CRYPTO_PKI: Error:  Code 0x0000 while selecting self signed certificate

CRYPTO_PKI: WARNING: Certificate, private key or CRL was not found while
verifying cert in message by issuer self-signed cert

CRYPTO_PKI: status = 324: failed to verify
CRYPTO_PKI: transaction GetCACert completed

I captured the traffic between the PIX and the OpenCA and the reply from the
OpenCA looks like that the root-ca-cert, Sub-CA-cert and the RA-cert have
been sent to the PIX. However, the PIX was probably not able to find out the
certs or keys.

My questions:

does anybody know whether it is possible to use OpenCA as Sub-CA for SCEP?
And how can I get more debugging information from the OpenCA side?

 Any idea would be appreciated.

best regrads
