Seems that I have found the problem. It is TLSv1.3, I have tried to connect with TLSv1.2 and connection was OK: [root@client01 ~]# openssl s_client -connect server2.ipa.unicc.org:636 -tls1_2 ...

Do you know why it is not working with TLSv1.3 and how can I fix it? I have still no luck with adding the server to IDM. I have followed the workaround described here: https://bugzilla.redhat.com/show_bug.cgi?id=1685470 now if I test the connection with: openssl s_client -connect server2.ipa.unicc.org:636 It connects using TLSv1.2, but it still not working the join to IDM.
