[Freeipa-users] ipa-client-install failing on new ipa-server

I'm referring to the host certificate; I was looking at the web UI, under
Identity->Hosts in the server details page. The Host Certificate section
says 'No Valid Certificate'.
The server has a /etc/krb5.keytab file, and on the same page the Enrollment
section says 'Kerberos Key Present, Host Provisioned'.

thx
anthony

thx
