I think the problem is figured out, though solution is not easy. Would some one
please open a bug for this problem.
Another close question to ask: Does this means the IPA PKI/CA system is still
in its beta/alpha stage, and better avoid in production IPA deployment?
I've see messages, Q/A in mail list of 389 Directory Server and freeIPA much,
much more often than the Dogtag. If so, I can use --selfsign to install IPA
masters and replicas now, and wait until the Dogtag is mature enough. because
this IPA solution is the core of our business authentication and authorization,
and so I have been asked several times to make it reliable and easy to
maintain. Otherwise the admin. official would rather to keep existing
Kerberos+OpenLDAP solution which is time proven.
Now the problem debugging is attached below:

Hi Rich and all,
the '-n ipaca' option doesn't work for CA certificate LDAP backend.

In general - you can use the .pl scripts when the server is running,
the non-.pl scripts when the server is down. So, use ldif2db.pl to do an
online import.
Also, with ipa, you can use -n userRoot or -n ipaca depending on if
this is the ipa instance or the CA instance.

db2ldif doesn't use file descriptors in the same way as the server
does when it is using them to listen and service incoming
connections - just ignore that message
