Good. But still, I am curious about your architecture. It almost looks like you are installing several FreeIPA servers (ipa-server-install), but with the same realm/domain. Can you share the reasoning? Maybe an advise can be given for the whole FreeIPA architecture.

It is not something expected, normally you would install one FreeIPA server with realm "" and then install replicas (ipa-replica-install) for redundancy or load balancing.

many thanks for this fix!

Hi, Martin

Many thanks for this info

My user and personal workstations have to remain on CentOS6 until IPA is
deployed across the board, when i think we might have better case for
migrating to EL7.  However, we also have loads of software with complex
dependencies in production that makes major version updates precarious

In answer to your question, yes, accessing these IPA servers from a fresh
user account that's never seen these sites before exhibits the exact same
issues whether in Firefox or Chrome - you ge the first one but the second
(and 3rd, 4th - as many as you have) will block

That idea of specifying a different timestamp in Subject when installing
secondary instances seems worth trying right now and will report back

I became aware the other day that building new IPA infrastructure on CentOS6
was seriously going to limit my ability to stay current with improvements, so
i've rebuilt my primary and secondary IPA hosts on CentOS7 (one day apart).
Installation went fine except that i cannot access one or the other host's UI
(Error code: sec_error_reused_issuer_and_serial). This was never an issue in
3.0 where i could access either in the same browser session

I rather think this is a problem of using the same browser against
reinstalled FreeIPA, which have the same CA subject and same serial as the
CentOS6 IPA, but different cert.

Related ticket with workaround:

Using Firefox (38) and Chrome (46) I can access any one of the 2 hosts in any
order on the first attempt (with Firefox only after deleting the previous
host's cert) but the second host will always be inaccessible with
ERR_SSL_SERVER_CERT_BAD_FORMAT. Chrome is similar, except it doesn't trust
either host's certificate (red-crossed-out https in URL). I've confirmed this
using a clean account as well.   My working environment is CentOS 6.6.

The Opera browser on the contrary sees both hosts equally well with zero

Is this behaviour by design or ?

This is certainly not by design, I think it is all about the browser. Did
you try the new CentOS7 with new browser or at least with a fresh Firefox
profile, if it also gives you cert error?
