UDP port checks in ipa-replica-conncheck are too strict. The entire conncheck fails when UDP ports cannot be verified as open. However, UDP protocol is unrealiable by its nature and the port can also not be checked if there is an application already bound to it. This can happen for example when ipa-replica-conncheck is run as a part of ipa-ca-install and the replica services are thus already running. This patch changes the behavior of UDP port checks. The conncheck script now rather reports a warning that UDP port cannot be verified but does not fail the entire test. https://fedorahosted.org/freeipa/ticket/2514
Ground rules on adding new schema Brand new schema, particularly when written specifically for IPA, should be added in share/*.ldif. Any new files need to be explicitly loaded in ipaserver/install/dsinstance.py. These simply get copied directly into the new instance schema directory. Existing schema (e.g. in an LDAP draft) may either be added as a separate ldif in share or as an update in the updates directory. The advantage of adding the schema as an update is if 389-ds ever adds the schema then the installation won't fail due to existing schema failing to load during bootstrap. If the new schema requires a new container then this should be added to install/bootstrap-template.ldif.
