我安装了Debian Squeeze和sssd.当我尝试通过ssh用户’alexwinner’登录服务器时,我在日志中看到：

(Fri May 11 18:56:03 2012) [[sssd[krb5_child[26281]]]] [get_and_save_tgt] (1): 523: [-1765328360][Preauthentication failed]

但是当我执行kinit alexwinner一切都好的时候,我收到了罚单.

这是我的sssd.conf

这是我的krb5.conf

[realms]

MYDOMAIN.COM = {

}

我试图看到tcpdump用于kerberos包,并且看到padata与login和kinit不同.

我能做什么？
