ssh登录问题

lxj821212

情况如下,我是在虚拟机做的系统,我以前做samba的LDAP 做到一半,我想用ssh连接主机,可以用root登录,却不可以用普通用户登录. 不知道是什么原因,我很菜,请教一下高手
日志文件如下:
Jan  8 20:21:09 localhost2 NetworkManager:

Jan  8 20:42:17 localhost2 sshd(pam_unix)[2424]: session opened for user root by root(uid=0)

这是我再一次登录时发生的日志
Jan 8 21:00:48  localhost2  last message  repeated 6 time
JAN 8 21:01:01 localhost2 crond(pam_unix [2507]:session opened for user root by (uid=0)
Jan 8 21:01:05 localhost2 sshd:pam_ldap: ldap_simple_bin Can't fontact LDAP server
还有我不清楚这个pam_ldap这个和ssh 和关吗．可以提供一些资料吗．谢谢
