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 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
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
either host's certificate (red-crossed-out https in URL). I've
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
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?
