NNO-00123:

node "string" has no authoritative parent, data ignored
Cause: an object in the domain data is apparently not in the domain(s) which the server is authoritative for. The record in question is not loaded, but the server continues to load data.
Action: Check for inconsistencies in the data and correct any errors in topology definition or domain data outside of authoritative domains.
