无法在Ubuntu 14.04上设置Kerberos – krb5kdc：没有这样的文件或目录 – 在为realm myrealm初始化数据库时

我正在尝试按照Ubuntu wiki上的指南来安装和设置Kerberos.我正在运行Ubuntu 14.04(LTS)64位.我已经设置了avahi-daemon以提供.local DNS名称.然后我跑了：

sudo apt-get install krb5-kdc krb5-admin-server

该对话框询问我一个领域,以及我输入的服务器的主机名.然而,它似乎遇到了一个错误：

krb5kdc: cannot initialize realm myrealm - see log file for details
...fail!

唯一的问题 – 没有日志文件.似乎默认的/etc/krb5.conf实际上没有启用日志记录.无论如何,我添加以下内容：

[logging]
    default = FILE:/var/log/krb5.log

然后尝试运行：

sudo dpkg-reconfigure krb5-kdc

它仍然出错,但这一次,在/var/log/krb5.log中,我看到：

krb5kdc: No such file or directory - while initializing database for realm myrealm

但是,它实际上并没有告诉我缺少哪个文件或目录.

这是我的krb5.conf

[libdefaults]
        default_realm = myrealm

        krb4_config = /etc/krb.conf

# The following encryption type specification will be used by MIT Kerberos
# if uncommented.  In general,the defaults in the MIT Kerberos code are
# correct and overriding these specifications only serves to disable new
# encryption types as they are added,creating interoperability problems.
#
# Thie only time when you might need to uncomment these lines and change
# the enctypes is if you have local software that will break on ticket
# caches containing ticket encryption types it doesn't kNow about (such as
# old versions of Sun Java).

这是我的/etc/krb5/kdc.conf文件：

对于发生了什么的任何想法？

您需要先创建一个数据库：

kdb5_util create -s -r myrealm
