I'm going through the JAAS tutorial at http://java.sun.com/j2se/1.4.1/docs/guide/security/jgss/tutorials/AcnAndAzn.html but I always get the error "Integrity check on decrypted field failed (31)" after attempting to auth to my redhat 8 kdc. 
 
Pointed at my slackware slave kdc with the mit-kerberos src build it works just fine.  The kdc configs are identical and rsh, rlogin, kinit work from both the redhat and slackware boxes.
 
Has redhat gimped something?

I've just added a new KDC slave to our kerberos setup.  When I run kprop
on the primary KDC to backup to the new slave it works the first time but
on subsequent runs it stops after the first "32768 bytes sent." message.
Looking in the logs I see the following message:

  kpropd: Message stream modified while decoding database size from client

I've looked this up on google but saw nothing that explained its cause.
Can anybody advise me as to what I should be looking at to try and fix
this problem?

I'm running MIT 1.2.7 on the Primary KDC and MIT 1.3.1 on the new
secondary KDC.  Kprop works with our existing slave which is also running
1.2.7.  I am hesitant to upgrade our primary KDC to 1.3.1 in case this
problem is due to a bug in that release.  All KDCs are running on
FreeBSD-STABLE.
