I have an ipa server and an ipa client both in 3.0.0-47. In order to connect via SSH to the host of the ipa-client, I use root.

Bahan </div></div></blockquote> I would firstly check the time difference between client and IPA server. If the time skew is too grea all sorts of errors can pop up regarding Kerberos authentication. I would also check /var/log/http/error_log and /var/log/dirsrv/slapd-<REALM>/errors for additional info. I suspect there is something wrong with the keytab of HTTP principal on the IPA server. -- Martin^3 Babinsky -- Manage your subscription for the Freeipa-users mailing list: <a href="https://www.redhat.com/mailman/listinfo/freeipa-users" rel="noreferrer" target="_blank">https://www.redhat.com/mailman/listinfo/freeipa-users</a> Go to <a href="http://freeipa.org" rel="noreferrer" target="_blank">http://freeipa.org</a> for more info on the project </blockquote></div> </div> </div></div></blockquote></div> </div>
