Problem Contact KDC

[mohamed.chaari@orange-ftgroup.com]

Hello,
I have installed kerberos v5 such as it is described in the guide. While
I send a erquest for a credential from a client, I use the function
"kinit".
The result is : "kinit(v5): Cannot contact any KDC for requested realm
while getting initial credentials"
The domain that I have is exactely example.com.

**In the file named.conf : 

zone "example.com" IN {
	type master;
	file "example.zone
	allow-update {none;};
};

**In the file example.zone:

....	IN SOA example.com. root.example.com. 
		...
		..
		IN NS		example.com
Kerberos	IN A 	192.168.1.254
...

Other files of Kerberos are not changed.

Can anyone help me please?

Thanks
