ubuntu下kerberos安装

1、安装kerberos所需要的包
sudo apt-get install krb5-user

2、备份kerberos配置文件
sudo cp /etc/krb5.conf /etc/krb5_back.conf

3、配置kerberos
修改/etc/krb5.conf，满足自己的需要

4、配置例子（修改EXAMPLE.COM、example.com等信息）
[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log

[libdefaults]
default_realm = EXAMPLE.COM
dns_lookup_realm = false
dns_lookup_kdc = false
ticket_lifetime = 24h
renew_lifetime = 7d
forwardable = true
[realms]
EXAMPLE.COM = {
  kdc = ukdc.example.com
admin_server = ukdc.example.com

}
[domain_realm]
.example.com = EXAMPLE.COM
example.com = EXAMPLE.COM
