Okay, getting back to this.  Looks like this behavior was introduced later.  I
installed with an earlier version of IPA.  Now trying to reproduce the install
with 4.1 I get the same error on ipa-server-install.

Looks like the new behavior came in:

    CA-less installer options usability fixes

    The --*_pkcs12 options of ipa-server-install and ipa-replica-prepare have
    been replaced by --*-cert-file options which accept multiple files.
    ipa-server-certinstall now accepts multiple files as well. The files are
    accepted in PEM and DER certificate, PKCS#7 certificate chain, PKCS#8 and
    raw private key and PKCS#12 formats.

    The --root-ca-file option of ipa-server-install has been replaced by
    --ca-cert-file option which accepts multiple files. The files are
    accepted in PEM and DER certificate and PKCS#7 certificate chain formats.

    The --*_pin options of ipa-server-install and ipa-replica-prepare have been
    renamed to --*-pin.

And is here (I added the root_logger.debug lines to figure out what is going 

        # Check we have the whole cert chain & the CA is in it
        root_logger.debug('get_trust_chain for %s' % (key_nickname))
        trust_chain = list(reversed(nssdb.get_trust_chain(key_nickname)))
        root_logger.debug('trust_chain =  %s' % (':'.join(trust_chain)))
        ca_cert = None
        for nickname in trust_chain[1:]:
            cert = nssdb.get_cert(nickname)
            if ca_cert is None:
                ca_cert = cert

            nss_cert = x509.load_certificate(cert, x509.DER)
            subject = DN(str(nss_cert.subject))
            issuer = DN(str(nss_cert.issuer))
            root_logger.debug('nickname =  %s, subject = %s, issuer = %s' %
(nickname, subject, issuer))
            del nss_cert

            if subject == issuer:
            raise ScriptError(
                "The full certificate chain is not present in %s" %
                (", ".join(cert_files)))

So the issue for us is as follows:

We are issued a wildcard cert for *.nwra.com from namecheap.com/COMODO SSL.
They issue us a cert and a certificate chain file that provides two certs to
chain back to:

CN=AddTrust External CA Root,OU=AddTrust External TTP Network,O=AddTrust AB,C=SE

This cert is in Firefox's certdb (and presumably other browsers) and so works.

FWIW - I don't seem to find this cert (or any AddTrust cert) in the openssl ca
certs in /etc/pki.

I'm not sure I follow the new logic.  In the past with ldap SSL trusts in 389
we've always simply installed the cert that signed the DS cert as a trusted CA
cert (via /etc/openldap/{,ca}certs).  I don't understand why we're now
insisting on having the issuer of the last cert in the DB.

But I am able to work with it by extracting the 'AddTrust External CA Root'
cert from firefox and then:

# openssl pkcs12 -export -in STAR_nwra_com.crt -inkey nwra.com.key -certfile
STAR_nwra_com.ca-bundle -out nwra.com.p12

(The ca-bundle is the one issued by namecheap with the two intermediate certs)

# ipa-server-install -r NWRA.COM -n nwra.com -p `cat /etc/ldap.secret` -a `cat
/etc/ldap.secret` --root-ca-file=AddTrustExternalCARoot
--dirsrv_pkcs12=nwra.com.p12 --dirsrv_pin=XXXXXX --http_pkcs12=nwra.com.p12
--http_pin=XXXXXX --idstart=8000

 But then when I go to make a replica:

# ipa-replica-prepare ipa1.nwra.com --dirsrv_pkcs12=nwra.com.p12
--dirsrv_pin=XXXXXX --http_pkcs12=nwra.com.p12 --http_pin=XXXXXX
Directory Manager (existing master) password:

(SEC_ERROR_LIBRARY_FAILURE) security library failure.

Which looks like others are experiencing (with not resolution that I could
see) https://www.redhat.com/archives/freeipa-users/2015-April/msg00514.html

Putting AddTrustExternalCARoot into nwra.com.p12 doesn't appear to help.
