Hi Oliver,

I think the invalid subject was just me using "XX" as country earlier.

I am writing my own SCEP client, which is why I am testing against different 
SCEP servers. I noticed (a bit too late ...) that many came around before the 
official RFC existed, so most are probably implementing some sort of draft. 
It's sometimes not so clear how to accomodate to all of them :( But I am happy 
I got it working with openxpki now.

Another question I have regarding this: most SCEP clients have a cert 
fingerprint configured that they trust. I'd expect this to be the fingerprint 
of the root cert (since I can then verify the whole chain against the root). It 
seems like macOS does it like this. However, apparently openxpki only later 
added the "include_root" parameter and previously did not send the root cert. 
Which fingerprint would you say clients should have configured then, just the 
one from the issuing CA cert? Isn't it possible that a client then blindly 
trusts an issuing cert, but the chain from that cert to the root is actually 
not valid?

Hi Immanuel,

the subject is create from the CN in the csr but there are no special 
restrictions on this - so as long as you have a CN set it should work, the 
assembly of the certificate is controlled by the profile definition so if you 
need something else you just need to change the configs.

The RenewalReq type was added "recently" to SCEP and as we did not yet see any 
customers using this in the wild it was not implemented but if this now comes 
along we will add support for it in one of the next releases. Might you tell us 
what client you are using?

For reference for future readers - we have updated the default configuration to 
better reflect such problems and put a README to the config repo that explains 
the basic parts: 
https://github.com/openxpki/openxpki-config/blob/community/scep/README.md

best regards

Oliver

Thanks Oliver, that made it work!

I still had an I18N_OPENXPKI_UI_ENROLLMENT_ERROR_SUBJECT_INVALID
error after that, but I fixed that by using a common name that looks like a 
hostname (not entirely sure what the rules here are).

It also looks like openxpki does not accept the message type RenewalReq, so I 
had to retry with PKCSReq instead for the renewal.

Maybe this is useful for someone else as well. Thanks again, I appreciate the 
quick help.

Hello Immanuel,


you very likley used the wrong SCEP adress - the systems comes with a special 
kind of autoconfiguration which currently does not properly handle cases when 
you use an incomplete config. The default config provides an endpoint named 
"generic", so you have to use the URL http://yourhost/scep/generic in your SCEP 
command.

Sorry for posting to GitHub first! I'll copy my text here:
Hello everyone. I followed the quickstart guide to setup the democa on a debian 
12 VM since I wanted to try out the SCEP workflow. I tried with different SCEP 
clients, also with sscep as it is described in the quickstart guide.
I can send getca / getcacaps requests, but the enrollment always fails with:

./sscep: pkistatus: FAILURE
./sscep: reason: Transaction not permitted or supported

The GUI shows me that the workflow failed with error "Invalid profile".
On the server side, I see this in the catchall log:

2025/02/04 14:11:26 openxpki.auth.INFO Login successful (user: Anonymous, role:

[pid=1536|user=Anonymous|role=System|sid=nAWV|wftype=certificate_enroll|wfid=15871|pki_realm=democa]

I don't get what I am supposed to do there. I am creating a CSR with the 
challenge password "SecretChallenge". I don't think a specific subject/common 
name is needed? The cert_profile is set to tls_server in 
/etc/openxpki/config.d/realm.tpl/scep/generic.yaml (I haven't touched these 
files so I assume they are all set up from the sampleconfig.sh).

I hope you can help me out here :)
