[Pki-users] CMC support

Hi - My question is a follow-on to the CMC enrollment thread from April 28. The earlier thread says CMC requests have to be inputted through the web based "certificate enrollment profiles" by filling in a form field with the request data. I noticed the Dogtag CA has servlets running at: /ee/ca/profileSubmitCMCFull /ee/ca/profileSubmitCMCSimple /ee/ca/CMCRevReq Is it possible for a client to send requests directly to those servlets instead of going through the web form -- and is there a way for the client to receive the CMC Response from the server as described in the RFC, rather than just the text message / base64 certificate returned by the web form after it is submitted? Also, do CMC requests always have to be signed by an authorized agent, or has there been any thought to allowing clients to rekey their own certificates directly with the CA? (e.g. authenticate a new certificate request using the old certificate with the same subject) Has interoperability been tested with any tools besides the ones described here http://pki.fedoraproject.org/wiki/PKI_Java_Tools (CMCEnroll/CMCRequest/etc.)? Do any other CMC clients actually exist? Thanks, Mike Peck
