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

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!
