Hi,

I've tried this several times and with several different methods and I can't get it to work. The certificate I have now is valid and I do have a green lock in my browser and all certificates in the chain is valid, but on DNA Center > Settings > Certificate the Authority for the cert still say Self-signed.

I've tried it just as shown in this video with an external OpenSSL. I've also try both the Openssl method and the API method described by Cisco here: https://www.cisco.com/c/en/us/td/docs/cloud-systems-management/network-a...

Nothing works.

NOTE: The default Subordinate Certification Authority template Cisco wants you to use does not work. It won't import the certificate because of missing keyEncipherment so I did create my own template with keyEncipherment and both serverAuth and clientAuth.

What version of DNAC are you running. Have you opened a case with Cisco to see if this is a bug?

I actually got this to work. I had to import the Root CA certificate into the DNA Trustpool manually. I noticed that it didn't do this during the process automatically so after I did that it shows up correctly. This happened with all the methods I tried.

Hello Metha. Thank you for this video !
Could you share the .cnf file please ?
I am facing issues with my file and I would like to compare.

Thank you,
Alex
