我正在 ubuntu 机器上安装 Kerberos5-1.12.1这些说明。
每当我尝试做的时候：
kinit user1
我遇到了一个错误：
kinit: Cannot contact any KDC for realm 'UBUNTU' while getting initial credentials
以下是我的 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_tkt_enctypes = des3-hmac-sha1

我的配置文件有问题吗？如果没有，谁能告诉我为什么会出现这个错误？
提前致谢...
答案1
虽然这是一个两年前的问题，但我还是给出了答案，因为我遇到过类似的问题。
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
就我而言，结果是重新启动 Windows 机器上的“Kerberos 密钥分发中心”服务，该服务要么被某人手动停止，要么崩溃了。
这可能与 Linux 端的问题完全相同——KDC 服务器无响应。
我希望它将来能够对某些人有所帮助。
答案2
[domain_realm]
.UBUNTU = UBUNTU
UBUNTU = UBUNTU

答案3
如果您安装了krb5-{admin-server,kdc}正确（apt-get install），那么你kdc.conf应该在/etc/krb5kdc/kdc.conf
另外，使用更好的 enctypes。现在不再是 90 年代了。
答案4
我知道这个问题已经发布很久了，但我想添加我的解决方案
确保在 etc/hosts 中添加了与 kdc 名称相同的主机名
希望这会对某人有所帮助，谢谢。
