前言

LDAP+NFS+Autofs也是一种网络用户集中管理解决方案，相对于NIS+NFS+Autofs而言，有着更可靠的安全性。

Ldap

LDAP(Lightweight Directory Access Protocol)轻量目录访问协议，它基于X.500标准的，与X.500不同，LDAP支持TCP/IP，这对访问Internet是必须的。LDAP的核心规范在RFC中都有定义，所有与LDAP相关的RFC都可以在LDAPman RFC网页中找到。

LDAP+NFS+autofs

ServerPost

step1.

yum install -y openldap openldap-clients openldap-servers

step2.Change the dynamic ldap config file.

mv slapd.d slapd.d.bak --> /etc/openldap

step3. Use the static ldap config file.

cp /usr/share/openldap-servers/slapd.conf.obsolete /etc/openldap/slapd.conf

step4. Edit the LDAP config file in the section “database definitions” as below:
vim /etc/openldap/slapd.conf

        # database definitions
        ################################################################

        database        bdb
        suffix          "dc=nice,dc=com"
        checkpoint      1024 15
        rootdn          "cn=Manager,dc=nice,dc=com"
        rootpw            fanguiju
        #################################################################
        #the meaning is assign the domain for storage the user account.
        #        cn=Manager-->ManagerAccount
        #        dc=nice,dc=com-->storage user account domain

step5. Edit the ldap domain database config file.

cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB__CONFIG

chown ldap:ldap DB_CONFIG

step6. Start ldap service

service ldap start
ldapsearch -x -b "dc=nice,dc=com"
        -x #简单明文方式发送

step6. Converting local user infomation into LDAP user infomation also storage the LDAP user infomation to the database file.

yum install -y migrationtools  --> migrationtools is a format conversion.

vim /usr/share/migrationtools/migrate_common.ph

        $DEFAULT_MAIL.DOMAIN="nice.com"
        $DEFAULT_BASE="dc=nice,dc=com"

Create base.ldif

 ./migrate_base.pl > base.ldif  #Converting the base info into LDAP info
 #Edit the base.ldif file as below(keep base item of nice,People,Group):
            dn: dc=nice,dc=com
            dc: nice
            objectClass: top
            objectClass: domain

            dn: ou=People,dc=nice,dc=com
            ou: People
            objectClass: top   
            objectClass: organizationalUnit

            dn: ou=Group,dc=nice,dc=com
            ou: Group
            objectClass: top
            objectClass: organizationalUnit

Create user.ldif

./migrate_passwd.pl /etc/passwd > user.ldif   #Converting the user info into LDAP info, if you want to keep therein some user ,you can cut the user info in the passwd file also storage it to new file.将要加入到LDAP的用户留下

Create group.ldif

./migrate_group.pl /etc/group > group.ldif    #Converting the group info into LDAP info, idem.

step7. After converting,import the LDAP info to the DB file.

ldapadd -D "cn=Manager,dc=nice,dc=com" -W -x -f base.ldif #input password of "jmilkfan".
ldapadd -D "cn=Manager,dc=nice,dc=com" -W -x -f user.ldif
ldapadd -D "cn=Manager,dc=nice,dc=com" -W -x -f group.ldif

step8. Test the LDAP config again.

ldapsearch -x -b "dc=nice,dc=com"

step9. Setup the PHP env (phpldapadmin)

yum install -y php php-ldap
tar phpldapadmin -C /var/www/html #Source code install phpldapadmin
cp /var/www/html/phpldapadmin/config/config.php.example /var/www/html/phpldapadmin/config/config.php

step10. Login phpldapadmin via web protal.

 http://localhost/phpldapadmin

step11. Create TLS(Transport Layer Security 安全传输协议) and check authentication certificate.

sh certcreate.sh #create certificate by certcreate.sh script

step12. Write TLS authentication certificate URL to the slap.conf.
vim /etc/openldap/slapd.conf

cp XXX.crt XXX.key /etc/openldap/certs
cp XXX.crt /var/www/html --> client can download the cert file

step13. Test the LDAP in clientPort.
Add LDAP domain by imaging and login the LDAP user.

step14. Setup the NFS
vim /etc/exports

/home    192.168.0.0/24(rw,sync)

Restart service

service nfs restart

step15. Setup the autofs
vim /etc/auto.master

/home    /etc/auto.ldap

cp /etc/auto.misc    /etc/auto.ldap

vim /etc/auto.ldap

*    -fstype==nfs,rw    LDAPServerIP:/home/&

Restart service

start autofs restart

step16. Test the LNA

su - LdapUserName
