Your assumptions is correct Alexander, I did accept the server cert otherwise the browser
won't open the login page at all. Beside, that log was there even before when it was
working...before the update.
Re to gssproxy, all my attempts were also followed by a full server reboot.
I will take a look at your article but I can certainly confirm the issue is upgrade
related. I am not the only one who is experiencing this from what I read on internet.
Thanks

Hi Fraser,
Thanks for the tips.
I did put SELinux in permissive mode and of course I have restarted the
IPA after that to makes sure the new setting picked up by IPA.
All certs including CA sanitized and they are correct with the trust
flags, so it is not matter with certs either. I read about the
SubjAltName warning and indeed I was ignoring that part.
I have raised the case with RedHat but no joy with them either. Usually
the community is the best way to solve this sort of issues as I never
have had good experience with redhat support to be honest.
So if anyone else has further suggestions pls fire up.
Your httpd's error_log says your _client_ does not trust the certificate. Can
you check the client browser actually trusts your CA?
I assume you did accept the server cert trust when Firefox or Chrome asked you, did you?
At least in Fedora and RHEL we configure Firefox to only allow GSSAPI negotiate over
https:// links with trusted certificates.
Another component to look at is gssproxy. You might want to restart gssproxy too when you
restarted IPA.
I have written an article how to debug FreeIPA 4.5.0:
Thanks a lot.
Stefan

One more thing; one the affected master try putting `debug = True` in
/etc/ipa/default.conf and restarting FreeIPA. You will get a lot more debug output in the
httpd logs which could help narrow down the problem.
