The OS is "Fedora release 25 (Twenty Five)". I compared the output from "ldapsearch -LLL...", it differs. But in order to make ipa0 work I temporarily broke connection between nodes (with iptables) so it's normal. Yhe date is [root@ipa0 ~]# date Sun Oct 20 19:46:18 MSK 2019
All the other certificates are valid. I use Let's Encrypt certificates and I rolled them back to the ones valid in October.
