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.
