I deliberately set the server back 2 years, installed Freeipa-Server, and then synchronized the time back.The related service certificate expires.Verify this:https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/htm... But it didn't work out. I confirm my modification: 1:less /etc/apache2/mods-enabled/nss.conf #add NSSEnforceValidCerts off 2:root@ipa-test-65-198:/home/liangrui# ldapsearch -h $(hostname) -p 389 -D "cn=directory manager" -w directorypassxx -LLL -b cn=config -s base "(objectclass=*)" nsslapd-validate-cert dn: cn=config nsslapd-validate-cert: warn You have restarted all services and rebooted the server.However, the result is still unable to use the relevant command root@ipa-test-65-198:/home# ipa user-find ipa: ERROR: cert validation failed for "CN=ipa-test-65-198.hiido.host.yydevops.com,O=YYDEVOPS.COM" ((SEC_ERROR_EXPIRED_CERTIFICATE) Peer's Certificate has expired.) ipa: ERROR: cannot connect to 'https://ipa-test-65-198.hiido.host.yydevops.com/ipa/json': (SEC_ERROR_EXPIRED_CERTIFICATE) Peer's Certificate has expired. What is the reason for this? Do I need to view or configure anything?For guidance, thank you My system is ubuntu16.04 and freeipa 4.3
