Description of problem: After selecting FreeIPA as authentication server in authconfig and marking checkbox 'Use DNS to locate KDC for realms' it would be good that the fields KDCs and 'Admin servers' are grayed out? Version-Release number of selected component (if applicable): authconfig-6.1.4-2.fc13.x86_64 How reproducible: Always Steps to Reproduce: 1. Just configure FreeIPA authentication with DNS used to locate KDCs. Additional info: In /etc/krb5.conf DNS resolution is selected and in the sam time values of KDC and admin server are filled with exact values. The question is which values have higher priority?
According to the krb5.conf manpage the DNS is used only when the realm and KDC is not filled in. I am not sure whether sssd behaves the same.
Jakub, can you clarify? I think our default behavior is the same, but you're the authority.
Yes, even though we don't have any equivalent of dns_lookup_kdc (which is the krb5.conf option set by the 'Use DNS to locate KDC for realms' checkbox), we always use service discovery when no KDCs are set. We don't have any equivalent of 'dns_lookup_realm' in SSSD at all - which is the second check box "Use DNS to resolve hosts to realms".
Kerberos realm is also retrieved from DNS, so it also should be either grayed out or maybe automatically filled in.
