I generated my signed certificate from Let’s Encrypt with the following site: https://gethttpsforfree.com/
I took the CSR of the WebAuth certificate from the WLC controller to be able to generate the signed certificate. Then, I add the root certificate which can be found on the site: https://letsencrypt.org/certs/isrgrootx1.pem.txt
after the intermediate certificate. I have my final certificate that contains:
- signed certificate
- intermediate certificate
- Root certificate
Impossible to put it on the cisco WLS controller. by looking more closely at the Root certificate provided by Let’s Encrypt to an issuer and a different subject from the intermediate certificate.
The intermediate certificate:
ISSUER: CN = DST Root CA X3,O = Digital Signature Trust Co
SUBJECT: CN= Let’s Encrypt Authority X3,0 = Let’s Encrypt, C = US
The Root certificate provided by Let’s Encrypt:
ISSUER: CN = ISRG Root X1,0 = Internet Security Research Group, C = US
SUBJECT: CN = ISRG Root X1.0 = Internet Security Research Group, C = US
How can I find the right Root certificate ( CN = DST Root CA X3,O = Digital Signature Trust Co) so I can push it on the controller?
Thanks and regards.
