GSSAPI, Cannot resolve network address for KDC in requested realm

[Amir Saad]

i use Fedora 4 , MIT Kerberos 5 , Cyrus-SASL 2.1.19 ,
 
i'm trying to run the client and the server samples but i got the following error with the sample-client:
****************************************************************************************************************************************
./sample-client -s host -n machine.mydomain.org -r
 DEMO.MYDOMAIN.ORG -u amir at DEMO.MYDOMAIN.ORG -p ../plugins/.li
****************************************************************************************************************************************
i'm trying to run the sample-client on the KDC machine (machine.mydomain.org )
 
i issued the command "hostname" and i got the following:
machine.mydomain.org 
 
kinit works and ping works with the KDC at machine.mydomain.org 
 
here is a part of the krb5.conf:
[realms]
 DEMO.MYDOMAIN.ORG= {
  kdc = machine.mydomain.org :88
  admin_server = machine.mydomain.org :749
  default_domain = example.com
 }

is there anyway to trace SASL logs? i mean i can't find any error messages although i edited the sysconf to direct all logs to a system.log file
 
i faced this problem before and it was a hostname problem but this time i'm 100% sure that the hostname is correct
 
i hope you can help
thanks for ur time
