$ kinit Administrator@DOMAIN.ALT kinit: Cannot find KDC for realm "DOMAIN.ALT" while getting initial credentials

It looks like something (NetworkManager?) inserts nameserver 8.8.8.8 entry into /etc/resolv.conf, thus SRV lookups fail:

$ host -t SRV _kerberos._udp.DOMAIN.ALT Host _kerberos._udp.DOMAIN.ALT not found: 3(NXDOMAIN) $ host -t SRV _kerberos._tcp.DOMAIN.ALT Host _kerberos._tcp.DOMAIN.ALT not found: 3(NXDOMAIN)

$ cat /etc/resolv.conf # Generated by resolvconf # Do not edit manually, use # /etc/net/ifaces//resolv.conf instead. domain domain.alt nameserver 8.8.8.8 nameserver 10.64.6.1

$ nmcli eth0: connected to System eth0 "Red Hat Virtio network device" ethernet (virtio_net), 2A:1E:D2:74:DC:1B, hw, mtu 1500 ip4 default inet4 10.64.86.100/24

Use "nmcli device show" to get complete information about known devices and "nmcli connection show" to get an overview on active connection profiles.

Consult nmcli(1) and nmcli-examples(5) manual pages for complete usage details.

5 maybe fix this, but it need testing. For example, when VM is resume from suspend this PR sometimes did not helps and recolv.conf containd servers from DHCP client.
