Right, there's no way to do it at a Kerberos level. There are various things that you can do within the service that's authenticating, but it may require development on your part. (For example, if you're authenticating the user via PAM, you could store the PAM failure count somewhere and reject logins to that user once the failures reach a particular threshold, something you could do without modifying anything about how Kerberos works.) Converting a failed authentication compromise into a denial of service attack is generally a stupid idea, IMO. Far better to start rejecting packets from a host that's apparently trying to do a dictionary attack. -- Russ Allbery ([EMAIL PROTECTED]) <http://www.eyrie.org/~eagle/> ________________________________________________ Kerberos mailing list [email protected] https://mailman.mit.edu/mailman/listinfo/kerberos
