Logan,

This error is generated by the Kerberos KDC when someone
tries to log on with a username which is not valid in the
Kerberos Realm. Likely a user who mis-typed his or her
username. Are you just getting this sporadically..? Or is
a filling your log? A few here and there are normal. When
you start getting 1000's you can worry
