kerberos5 1.3.1

[sam]

Dear all,

I downloaded kerberos 5 1.3.1 from MIT, after installed it, the kdb5_util
has some problem with creating a realm:

root at sec [6:30pm] [/var/heimdal]# /usr/local/sbin/kdb5_util create -r
SEC.ROCK.COM -s
Syntax error in profile relation while retreiving configuration parameters
root at sec [6:30pm] [/var/heimdal]#

Here is my /etc/krb5.conf file:
root at sec [6:30pm] [...src/util]# cat /etc/krb5.conf
[libdefaults]
    ticket_lifetime = 600
    default_realm = SEC.ROCK.COM
    default_tkt_enctypes = des-cbc-crc
    default_tgs_enctypes = des-cbc-crc

[realms]
    SEC.ROCK.COM = {
        kdc = kerberos.rock.com:88
        admin_server = kerberos.rock.com:749
        default_domain = rock.com
    }

[domain_realm]
    .rock.com = SEC.ROCK.COM
    rock.com = SEC.ROCK.COM

Here is my named file  (db.rock):
root at sec [6:32pm] [...src/util]# cat /var/named/standard/db.rock
$TTL 6h
@ IN  SOA sec.rock.com. root.sec.rock.com. (
                        14
                        3600
                        900
                        3600000
                        3600 )
  IN  NS  sec.rock.com.

localhost               IN      A       127.0.0.1

sec                    IN      A       192.168.1.254

kerberos                CNAME 192.168.1.254

_kerberos               TXT  "ROCK.COM"
_kerberos._udp          SRV  0 0 88 sec
_kerberos-master._udp   SRV  0 0 88 sec
_kerberos-adm._tcp      SRV  0 0 749 sec
_kpasswd._udp           SRV  0 0 464 sec

What is wrong with my configure files?

Thanks
