[Pki-users] Dogtag PKI CA not enrolling router with CN or when IP specified in Trustpoint confg

Thu Dec 10 17:37:16 UTC 2020

Hi Christian,

Thanks for following up.

You are correct, I have testing UID/PWD auth with SCEP and that is working fine.

As mentioned the only reason I am not able to use this method, is because the UID/IP address is using the DHCP assigned uplink IP address. For my solution we need a more deterministic UID, as such I was attempting to use the CN/PWD auth with SCEP.

The way I setup the CN/PWD auth with SCEP is first get a working UID/PWD auth with SCEP setup.
Then edit the “…/ca/CS.cfg”:
auths.instance.flatFileAuth.authAttributes=PWD
auths.instance.flatFileAuth.deferOnFailure=true
auths.instance.flatFileAuth.fileName=/var/lib/pki/pki-tomcat/conf/ca/flatfile.txt
auths.instance.flatFileAuth.keyAttributes=CN
auths.instance.flatFileAuth.pluginName=FlatFileAuth

Then edit the “…/ca/flatfile.txt”:

CN:dev-sec-a-2.example.com
PWD:password

Then I restart the service and test.

Cheers,
Rohan

Hi Rohan,
I have only played with IP UID/PWD auth with SCEP, which I just tried and seems to be working.
Could you maybe give me info on how you set up CN/PWD and I could look into that.

thanks,
Christina

Hello,

I am looking for some guidance/assistance with  a dogtag-pki CA server setup that I am testing.

Environment:
Cisco ASR router
CentOS 7 vm
PKI version 10.5.18-7.e17 installed
Configured to use flatfile to authenticate Cisco router using UID/PWD via SCEP
I am able to successfully authenticate and enroll the router via SCEP using UID/PWD in flatfile

Issue:
The UID=IP-address of the router interface toward the CA server, this IP is assigned via DHCP, thus not deterministic.
When I configured an IP address of a Loopback interface under the Trustpoint configuration of the router I can see that it seen by the CA in the logs but it is not used for authentication/enroll
I tried to change the CS.cfg file to use the CN/PWD to authenticate, however it appears I may have missed something as it fails with a password null.

Can you please assist with providing one of two options:

  1.  How to authenticate/enroll router via Loopback interface IP address that is specified in the Trustpoint configuration of the router?
  2.  How to authenticate/enroll the router using the CN/PWD in the flatfile?

Thanks in advance for  your assistance!
