kinit:在获得初始凭据时无法联系任何领域“UBUNTU”的KDC。

Question

我正在用这些指示在ubuntu机器上安装Kerberos5-1.12.1。

每当我想做的时候：

kinit user1

我正面临一个错误：

kinit: Cannot contact any KDC for realm 'UBUNTU' while getting initial credentials

下面是我的krb5.conf和kdc.conf文件：

/etc/krb5.conf:

[libdefaults]
        default_realm = UBUNTU

# The following krb5.conf variables are only for MIT Kerberos.
        krb4_config = /etc/krb.conf
        krb4_realms = /etc/krb.realms
        kdc_timesync = 1
        ccache_type = 4
        forwardable = true
        proxiable = true

# 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).

#       default_tgs_enctypes = des3-hmac-sha1
#       default_tkt_enctypes = des3-hmac-sha1
#       permitted_enctypes = des3-hmac-sha1

# The following libdefaults parameters are only for Heimdal Kerberos.

我的配置文件有什么问题吗？如果没有，请告诉我为什么会有这个错误？？

提前谢谢..。

Answer 2

虽然这是一个有两年历史的问题，但我要回答这个问题，因为我也有类似的问题。

LX-141(root)# root/greg>net ads join -S W12R2-C17.jamie_ad1.net -U Administrator%pwd
kerberos_kinit_password Administrator@JAMIE_AD1.NET failed: Cannot contact any KDC for requested realm
Failed to join domain: failed to connect to AD: Cannot contact any KDC for requested realm

在我的例子中，结果是重新启动Windows机器上的"Kerberos密钥分发中心“服务，该服务要么被人手动停止，要么崩溃。

这可能与Linux端的问题完全相同--没有响应的KDC服务器。

我希望这能对将来的人有所帮助。

如果您正确安装了krb5-{admin-server,kdc} (apt-get install)，那么您的kdc.conf应该位于/etc/krb5kdc/kdc.conf

此外，使用更好的封套。不再是90岁的S了。
