Kadmin: Incorrect Password while initilizing kadmin interface

[jagadish ks]

hi,

I am trying to configure kerberos version krb5-1.6 on a linux system with
Federo core 4 with root login in a network. I could able to create master
database with the command

kdb5_util create -r EXAMPLE.COM -s

aaded the principal to the database with the command

kadmin.local
kadmin.local: addprinc root/admin at EXAMPLE.COM
.
.
.
principal root/admin at EXAMPLE.COM created.

created the kadmin keytab.

when i am trying to run the master database with the commands i am facing
some problems.

%shell> krb5kdc

the log file will have the error message like

Apr 10 21:49:28 localhost krb5kdc[11849](info): setting up network...
