Почему ?
Cannot resolve network address for KDC in requested realm

Если все нормально разрешается на машине

host TC.LOCAL
TC.LOCAL has address 192.168.0.250
TC.LOCAL has address 192.168.0.251
host pdc
pdc.TC.LOCAL has address 192.168.0.250

cat /etc/hosts

cat /etc/krb5.conf

[libdefaults]
        default_realm = TC.LOCAL
[realms]
        TC.LOCAL = {
                kdc = 192.168.0.250
                admin_server = 192.168.0.250
        }

[logging]
        kdc = FILE:/var/log/krb5kdc.log
        admin_server = FILE:/var/log/kadmind.log
        default = FILE:/var/log/krb5libs.log

уже даже в krb5.conf прописал ip-ки.

почему он ругается?
