HI
Installed a fresh IPA server on CentOS 6 and all services are up and running. While trying to create database for the first-time, i am facing following error.

 # /usr/sbin/kdb5_util create -r TESTLAB.ORG  -s
Loading random data
Initializing database '/var/kerberos/krb5kdc/principal' for realm '
TESTLAB.ORG  ',
master key name 'K/M@
TESTLAB.ORG  '
You will be prompted for the database Master Password.
It is important that you NOT FORGET this password.
Enter KDC database master key:
Re-enter KDC database master key to verify:
kdb5_util: Kerberos database constraints violated while adding entries to the database 

Facing the same error while trying to create a principal:

# kadmin.local -q "add_principal -randkey reader@ TESTLAB.ORG "
Authenticating as principal admin/admin@ TESTLAB.ORG with password.
WARNING: no policy specified for reader@ TESTLAB.ORG ; defaulting to no policy
add_principal: Kerberos database constraints violated while creating "reader@ TESTLAB.ORG ".

Can anyone point to me the exact reason for the error ?

Regards
