I should also note that /var/log/dirsrv/slapd-PRIVATE-NET/errors ends with a series of "csngen_new_csn - Warning: too much time skew (-2153860 secs). Current seqnum=1" errors.

I think I've found a deeper problem, in that I can't update these because IPA simply won't start at all now.

I mistyped one of these -- the 2016-03-11 is actually 2018-03-11, and 2016-04-01 is actually 2036-04-01.

As for the unknowns, the first says status: CA_REJECTED and the error says "hostname in subject of request 'zw198.private.net' does not match principal hostname 'private.net'", with stuck: yes.

The second is similar, but for a different host.

No idea what's wrong with the rest, or why nothing will start. Near as I can tell, Kerberos is failing to start, which is causing everything else to go toes up.

Early in the startup, in /var/log/messages, there's:

ns-slapd: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (No Kerberos credentials available)

After that, I get a jar file read pboelm on log4j.jar, then a series of property setting attempts that don't find matching properties. Then some cipher errors, then it looks like named starts up okay, and everything pauses for about 5 minutes before it all comes crashing back down.

So some got updated and most didn't. Is there a recommended way to update these
all? The system is still backdated to 3 April (ntpd disabled) at this point.
It's usually good to start renewing(when it doesn't happen automatically
from some reason) with the cert which is about to expired first, i.e.
the one with "2016-03-11 13:04:29"

The process is:
- move date before the cert is about to expired
- leave it up to certmonger or manually force resubmit by `getcert
resubmit -i $REQUEST_ID`, where request ID is in `getcert list` output.

I'm little worried about the fact that CA cert was renewed at date which
is after expiration of the other certs.

Also the `expires: unknown` doesn't look good. Check `getcert list`
output for errors related to the cert.

On our non-CA IPA server, this is happening, in case it's related and

I would start with checking on all IPA servers if and what certificates

    # getcert list

    # getcert list | grep expires

When CA cert is renewed, it is not automatically transfered to clients.
There one must run:

I rebooted the server just in case, and it's still getting stuck at the same

I have an IPA server on a private network which has apparently run into

This morning, the gui started giving:

IPA Error 907: NetworkError with description "cannot connect to

I dug into the logs and after trying to restart ipa using ipactl, there was a
length pause, then:

and then things start shutting down. I can't start ipa at all using ipactl.

So at present, our DNS is down. Authentication should work for a while, but
I'd like to get this working again as quickly as possible. Any ideas? I deal
with certificates so infrequently (like only when something like this
happens) that I'm not sure where to start.

Thanks!
