    Or are you rather asking for specific PKI instructions?

I read the suggested document, previously, but its an excellent shared
reference for this discussion.

I have successfully submitted and approved the csr. Dogtag provides a
web UI which provides a Base 64 encoded certificate or Base 64 encoded
certificate with CA certificate chain in pkcs7 format.

For the servercert2010601.pem (the signed CSR request signing CA
certificate 0x9) referenced in the article, do I  copy and paste
(-----BEGIN .. END-----) the base 64 (not pkcs7) to a file using *.pem
then submit using one of the two --external-cert-file?

For the cacert.pem (the Root CA signing certificate 0x1) referenced in
the article, do I copy and paste the base 64 with ca in pkcs7 format to
a file using *.pkcs7 (or pem or does it matter?) then submit using the
second --external-cert-file?

Your guidance is much appreciated.

Hi Richard,

I tested the following steps to install FreeIPA with a certificate signed by an external Dogtag instance:

1- IPA installation on host ipaserver with:
ipaserver$ ipa-server-install [options] --external-ca

This step produces the Certificate Signing Request /root/ipa.csr that must be provided to the Dogtag server.

2- On the Dogtag machine, configure Dogtag client authentication (to be able to use the command-line):

dogtagsrv$ pki -c password client-init

This step creates a NSSDB in ~/.dogtag/nssdb where the certificates for client->dogtag server authentication will be stored.

dogtagsrv$ pk12util -i /root/.dogtag/pki-tomcat/ca_admin_cert.p12 -d /root/.dogtag/nssdb/

This step imports the caadmin certificate that was created during Dogtag installation into the client NSSDB. The client will be able to authenticate as "caadmin" when using Dogtag CLI. Please note the certicate nickname that can be found using

dogtagsrv$ certutil -L -d ~/.dogtag/nssdb/
PKI Administrator for <security domain>         u,u,u

3- On the Dogtag machine, submit the CSR and approve:
dogtagsrv$ pki ca-cert-request-submit --profile caCACert --request-type pkcs10 --csr-file /path/to/ipa.csr

This step submits the csr to Dogtag, using the caCACert profile in order to produce a Certificate that can be used for a Certificate Authority. Note the Request ID in the output as it will be used in the next command to approve the CSR and produce the cert:

dogtagsrv$ pki -c password -d ~/.dogtag/nssdb/ -n "PKI Administrator for <security domain>" cert-request-review <id> --action approve

4- On the Dogtag machine, export the certificate and the dogtag CA cert:

dogtagsrv$ pki -c password -d ~/.dogtag/nssdb/ -n "PKI Administrator for <security domain>" cert-show 7 --encoded --output ipa.cert
dogtagsrv$ pki ca-cert-show 1 --encoded --output dogtagca.cert

5- Resume ipa server installation with

ipaserver$ ipa-server-install --external-cert-file=ipa.cert --external-cert-file=dogtagca.cert

With those steps, I was able to install FreeIPA server with a 3rd-party signed Certificate Authority. Please let me known if you have issues with those instructions,
