Kinit/kadmin does not work

[Tadoori (EXT), Vilas]

Dear All,
 
It is really strange that the kinit does not work for me.
I am pretty confident about my krb5.conf and kdc.conf files.
They are good on the linux suse but when I have acutally started working
over the weekend ...it gives me this message as below for the kinit(on
solaris)
 
bash-3.00# kinit
kinit(v5): Cannot find KDC for requested realm while getting initial
credentials
 
The kadmin also is acting strange
 
bash-3.00# kadmin -p x_tadoor
Authenticating as principal x_tadoor with password.
Password for x_tadoor at XXXXXXXXX *
kadmin: Communication failure with server while initializing kadmin
interface

* intentionally crossed the realm
 
 
This is giving problems on the SunOS x 86 architecture.
 
bash-3.00# uname -a
SunOS hysuntcsso 5.10 Generic_118855-33 i86pc i386 i86pc

This is really frustrating....any help will be greatly appreciated.
 
Regards
Vilas
