acquiring creds for different principal ??

[vj]

By default the last part of hte host domain name in caps will be taken
as your realm.

how about this one :

 [libdefaults]
        default_realm = DE.COM

[realms]
        DE.COM = {
                kdc = dchyd1.hyd.de.com
                admin_server = dchyd1.hyd.de.com
        }

[domain_realm]
        hyd.de.com = DE.COM 
        .hyd.de.com = DE.COM
