> Kerberos works ok in kinit and kvno with the keytab.
> Some people said it's DNS or /etc/hosts problem, but nslookup was ok with ip
> and hostname
> and /etc/hosts is:
> 127.0.0.1 myhost localhost
> # The following lines are desirable for IPv6 capable hosts
> ::1 ip6-localhost ip6-loopback
> fe00::0 ip6-localnet
> ff00::0 ip6-mcastprefix
> ff02::1 ip6-allnodes
> ff02::2 ip6-allrouters
> I tested it with the host's ip too.
