Help: noaddresses help

[Jeet Joshi]

Hi

Sorry for the repetition.

I can ssh from the same network with GSSAPI. But I am not able to login from
other network without root password.

Here are some details--
on server side-->

[root at vmainkdc ~]#


On my gateway PC, 2 IP addresses are 192.168.20.1 and 192.168.0.4
My ssh client is on 192.168.0.14 and ssh server and kdc is on 192.168.20.20


krb5.conf on server file is

[libdefaults]
 default_realm = EXAMPLE.COM
 dns_lookup_realm = false
 dns_lookup_kdc = false
 noaddresses =    true
 forwardable = true
 proxiable = true
[realms]
    EXAMPLE.COM = {
  kdc = 192.168.20.20:88
  admin_server = 192.168.20.20:749
    default_domain=example.com
    }
[domain_realm]
    .example.com = EXAMPLE.COM
[logging]
    kdc = FILE:/var/log/krb5kdc.log
    admin_server = FILE:/var/log/kadmind.log
    default = FILE:/var/log/krb5lib.log


kinit from 192.168.0.14 is giving me ticket with
addresses = [none]
when "I do klist -a -n".

What is meaning of  "Wrong principal in request"?
I am using same principal by which I am able to login from 192.168.20.1
Please Help me if any other setting is required?


Thanks
Jeet
