[Freeipa-users] ipactl services running, but auth not working

Tue Feb 7 03:25:11 UTC 2017

It sounds like your IPA service is hanging.  The fastest way to check is do an ldap search against that host to see if it replies.  If it doesn’t look under /var/log/dirvsrv/sapd-$INSTANCE-NAME/error to see if you have an error.  I’ve seen this with the out of fd error, or if you server is in a dead lock.

there are reports from multiple clients being unable to authenticate.
ipactl status shows all services as running.
The problem is fixed when I 'ipactl restart'.

What exactly are you seeing to determine that the server is actually failing?  Is it not possible that sssd (the client) is timing out?  Will 389ds service an LDAP request, i.e. can you run

ldapsearch -D "cn=Directory Manager" -w <pw> -s base -b "cn=config" "(objectclass=*)”

What exactly are you trying to do?  Just password authentication to an sssd client?  Are you operating in a trusted AD environment?

My problem is with the server itself seemingly not providing services even though it claims to do so. would be curious to know what to look at on freeipa server or how to inrease logging

Have you looked at the sssd logs yet?

We have multiple ipa servers but only one is continuously affected by the strange problem described in the subject line.
Users report not being able to login to servers that are using a specific ipa_server. Looking at this server ipactl shows
everything as RUNNING. ipactl restart fixes the issue until the next time.

My questions are:
1. What could be causing this, and what can I check.
2. What logging should I enable on the server.
3. We are currently monitoring for processes 'Running' but clearly that is not fool-proof way to check if the service is actually up.
What would be a definitive method to check if Freeipa is up and functional in all respects. I was thinking of setting up cron job
that attempts to do kinit <fakeUserid> on a client machine. The problems that I foresee with this method is caching that might give false negatives.

thanks
