Hello,


is it possible to get 3rd CA (we were thinking of doing so) and following https://www.freeipa.org/page/Using_3rd_part_certificates_for_HTTP/LDAP will help me resolve this?


thank you,

regards,

Bhavin

Hello Rob,


here what we have. Looks like /etc/http/alias certificate is different, as it is from Sug 03 2014 through Aug 03 2034, which is original date.

How can we promote or update all the certificates on first master, then replica and client? Will we have to reboot or re-install client?

thank you and with regards,

It gets added as part of ipa-client-install, after the point where it is
failing.

This leads me to believe you don't have the "right" CA certificate after
all.

Is your Apache web cert signed by the IPA CA or a 3rd party? If by IPA
then I'd compare the CA cert in the NSS db in /etc/httpd/alias with the
one you have in LDAP.

mod_nss won't let Apache start with a bad cert chain.
