Hi,

I think this is similar to
https://lists.fedorahosted.org/archives/list/[email protected]/thread/37NX3YMIU5JHNFMVVHJXJCK7ZLVB5QOW/

As said in the other thread I think the worst case is that not all
possible KDC names are added to a kdcinfo file. So far I was not able to
reproduce the issue locally. Are you seeing this log message at regular
intervals or only once in a while?

bye,
Sumit
