While I was trying to import certificates into AADDS to secure the LDAPS service. I read the instructions (CN=<domain name> etc.) on how to do this. Self-signed certificates were working fine but I failed to import certificates issued and signed by Let's Encrypt. There is no error message in the Azure console. I triple checked the subject and SAN and they are 100% identical to the ones of my self-signed.
Any idea on why certs from Let's Encrypt get rejected? Has anyone experienced similar behaviour?
