Install postgresql on OpenBSD 4.5

[J�rg Klein]

Hello,
I try to install postgresql on OpenBSD.

less /usr/local/share/doc/postgresql/README.OpenBSD

Kerberos authentication

By default the postgresql server requires it's own krb5.keytab file. It
should be readable only by the _postgresql user. The default location of
the file is '/etc/postgresql/krb5.keytab' but is tunable by setting the
krb_server_keyfile line in postgresql.conf.

To generate the keytab:

# mkdir /etc/postgresql
# ktutil -k /etc/postgresql/krb5.keytab get postgres/server.domain
# chown _postgresql:_postgresql /etc/postgresql/krb5.keytab

I try this:
# ktutil -k /etc/postgresql/krb5.keytab get postgres/server.domain

The answer is:
ktutil: kadm5_init_with_password: Cannot contact any KDC for requested realm

What I do wrong?

Thank you for the help!
