This should really work like a charm, and I'm sure it is a stupid mistake of mine if it doesn't, but I really can't find out what goes wrong.

Both IPA server and client are on FC21, very up to date.
Server installation (standard, with dns) worked well. Required ports open in the firewall. Everything seems to work.

I did try to use the IPA server as a DNS (with forwarders) and NTP server from non-ipa clients, no problem. I also tried to use it as LDAP server, from a non-fedora machine (a synology). It worked well and I could see users.

When trying to enroll a client, the enrollment itself seems to succeed, but:
- Unable to sync time with NTP server
- Unable to update DNS
- Unable to find users

I include below the short installation log (I changed the real domain into hq.example.com <http://hq.example.com>), and in attachment, the full log with debug on.

From the debug log, about the DNS update failure, I can see this:

  ; Communication with failed: operation canceled
  could not reach any name server

I'm not sure what communication problem this could be, as the server (which is both the IPA and the DNS servers), clearly can be reached.

Any idea where to look at?

Do you have the IPA DNS server in the resolv.conf of the client?
