AIX5.2基于LDAP的用户管理

　　第一步，在 AIX5.2上的初始安装

　　建立用户认证所需要的所有代码都位于AIX系统安装光盘里，要求AIX的文件集bos.rte.security的版本必须是 AIX 5.2.0.2以上。首先要用AIX操作系统光盘来安装LDAP，同时也安装了DB2。需要安装的文件集如下所示：

　　# lslpp -l | grep ldap

　　Path: /etc/objrepos

　　bos.rte.security 5.2.0.0 COMMITTED Base Security Function

　　第二步，在AIX5.2系统上配置服务器

　　注意:1.环境变量LANG是很重要的，使用不同于en_US的LANG变量可能会发生很多问题，建议执行如下命令：

　　# export LANG=en_US

　　2.要保证/home文件系统有至少35MB的空闲空间

　　按照下面的步骤来配置服务器和客户机

　　1. 运行mksecldap命令来建立服务器

　　这将开始给LDAP目录树分派一个密码，启动slapd子系统并且从本地的/etc/security/passwd文件里调用AIX用户，这些也能在后面手动添加。这下面的例子里我们选择使用RFC2307认证协议。

　　root@regatta01

　　[/tmp]# mksecldap -s -a cn=admin -p just4ldap -S rfc2307aix

　　File System size changed to 262144

　　Creating the directory DB2 default database.

　　This operation may take a few minutes.

　　Cannot open message catalog file ldapadm.cat.

　　modifying entry cn=schema

　　migrating users/groups to LDAP server.

　　2.运行mksecldap -c命令建立客户机

　　在相同主机上使用“ -h localhost”参数, 如果是在别的主机上请使用这个参数指向LDAP服务器。

　　# mksecldap -c -a cn=admin -p just4ldap -h localhost -S rfc2307aix

　　3.使用lsuser命令来检查看是否数据库被调用

　　# lsuser -R LDAP ALL

　　daemon id=1 pgrp=staff groups=staff,daemon home=/etc login=true ...

　　...

　　4. 添加一个新LDAP用户

　　# mkuser -R LDAP testu1

　　# chuser registry=LDAP SYSTEM=LDAP testu1

　　# passwd -R LDAP testu1

　　Changing password for "testu1"

　　testu1's New password:

　　Enter the new password again:

　　# lsuser testu1

　　testu1 id=219 pgrp=staff groups=staff home=/home/testu1...

　　registry=LDAP SYSTEM=LDAP

　　# lsuser -R LDAP testu1

　　testu1 id=219 pgrp=staff groups=staff home=/home/testu1 ...

　　registry=LDAP SYSTEM=LDAP

　　# grep testu1 /etc/security/*

　　/etc/security/user:

　　testu1:

　　SYSTEM = "LDAP"

　　registry = LDAP

　　注意：没有 /etc/security/passwd条目

　　5. 以新用户身份登录系统

　　AIX Version 5

　　(C) Copyrights by IBM and by others 1982, 2002.

　　login: testu1

　　testu1's Password:

　　You are required to change your password. Please choose a new one.

　　testu1's New password:

　　Re-enter testu1's new password:

　　下面是显示了当用户testu1登录时,跟踪到的389端口（ldap的端口）发生的通信情况：
