You can ignore "invalid nonce" errors as those are actually normal for 
digest operation - the server expires nonce values after 15 minutes and 
then records the invlid error when the client next tries to use it. The 
client recovers by re-doing digest with a new nonce that the server 
provided. As long as you are not seeing authentication errors on the 
clients themselves, things are fine with that.

For Kerberos, the keytab error during startup means that your server 
machine is not properly Kerberized, and hence Kerberos is disabled.
