error principal in kerberos propagation

[chechu chechu]

hi¡

I follow the instructions from this howto to build the replication
server for kerberos...
http://www.tldp.org/HOWTO/Kerberos-Infrastructure-HOWTO/server-replication.html
	Everything went right untill :

/usr/Kerberos/sbin/kprop -f /var/Kerberos/krb5kdc/slave_datatrans
kerberos2.gnud.ie > /dev/null

where i got this error:

kprop: Server rejected authentication (during sendauth exchange) while
authenticating to server
Generic remote error: Wrong principal in request

I looked the logs and kerberos gives the right tickets when it executes,
in the slave server in syslog appears this 
Oct 20 23:32:21 shinobi kpropd[1390]: Connection from 192.168.2.3
Oct 20 23:32:21 shinobi kpropd[1390]: Error in krb5_recvauth: Wrong
principal in request

I have all the principals, that the howto says, creates and i add the
key to the keytab and send it to the slave...
someone can help me

thanks
