Problem to get TGT by des-cbc-md5 encrytype from Krb5-1.5.4 KDC on suse 10.

[Leo Li]

Hi, all
     I have a problem to get TGT while des-cbc-md5 enctypes from MIT
Krb5-1.5.4 KDC installed on suse 10.
     Here is the kdc.conf:

[kdcdefaults]
kdc_ports = 88

[realms]
EXAMPLE.COM <http://example.com/> = {
database_name = /usr/local/var/krb5kdc/principal
admin_keytab = FILE:/usr/local/var/krb5kdc/kadm5.keytab
acl_file = /usr/local/var/krb5kdc/kadm5.acl
kdc_ports = 88
max_life = 10h 0m 0s
max_renewable_life = 7d 0h 0m 0s
                supported_enctypes = des3-hmac-sha1:normal
arcfour-hmac:normal des-hmac-sha1:normal des-cbc-md5:normal
des-cbc-crc:normal des-cbc-crc:v4 des-cbc-crc:afs3
}

And the krb5.conf has :

[libdefaults]
default_realm = EXAMPLE.COM <http://example.com/>
dns_lookup_realm = false
dns_lookup_kdc = false
ticket_lifetime = 24h
forwardable = yes
default_tkt_enctypes = des-cbc-md5

[realms]
EXAMPLE.COM <http://example.com/> = {
  kdc = leo-suse.cn.ibm.com:88
  admin_server = leo-suse.cn.ibm.com:749
  default_domain = leo-suse.cn.ibm.com
}

[domain_realm]
.leo-suse.cn.ibm.com = EXAMPLE.COM <http://example.com/>
leo-suse.cn.ibm.com = EXAMPLE.COM <http://example.com/>

And then if I run
       kinit test at EXAMPLE.COM
It complains:
       kinit(v5): KDC has no support for encryption type while getting
initial credentials

I also have added the des-cbc-md5 enctype as a keytab for test at EXAMPLE.COMby:
       kadmin.local:  addprinc -e "des-cbc-md5:normal" test at EXAMPLE.COM
And the getprinc also shows:
       kadmin.local:  getprinc test at EXAMPLE.COM
       ...
       Number of keys: 1
       Key: vno 1, DES cbc mode with RSA-MD5, no salt
       Attributes:
       Policy: [none]

Besides, seems other encryption types are all supported, for example, the
des-cbc-md4.

So could somebody help to spot what is the problem?

Thanks in advance.
