rh9和rhel as 3的kerberos配置中遇到的问题

gxing

rh9内置kerberos 1.2.7
参考
Kerberos: The Definitive Guide
配置了一下
$ kdb5_util create -s
$ kadmin.local
addprinc gxing/admin
/etc/init.d/krb5kdc start
这些过程都没有问题
$ kinit
总是报：
Cannot find KDC for requested realm while getting initial credentials
google了半天，都说的都不得要领
最后从Kerberos: The Definitive Guide 有如下一段话：

Ensure that local systems' /etc/hosts file, if used, map the hostname to a valid IP address
Some systems install an /etc/hosts file with an entry such as this:
127.0.0.1              bigserver.wedgie.org   bigserver
This line, which maps the system's hostname to the loopback interface, will most likely cause problems at some point. You should ensure that if an /etc/hosts file is used, that all machine names point to real, network-accessible IP addresses. For example, if bigserver.wedgie.org's IP address is 192.168.1.1, then the /etc/hosts file should contain the following entries:
127.0.0.1                          localhost   bigserver
192.168.1.1                        bigserver.wedgie.org  bigserver我的hosts中就算有上述的异常情况，改动后一切正常。注 RHEL AS3中遇到了同样的问题。
