install OpenLDAP on CentOS6

1. 使用yum安裝openldap-servers(slapd)和openldap-client(ldap)
yum install openldap-servers openldap-clients

2. 編輯or產生/etc/openldap/ldap.conf
vi /etc/openldap/ldap.conf

URI ldap://127.0.0.1
BASE dc=my-domain,dc=com

3. 複製slapd.conf和DB_CONFIG

cp /usr/share/openldap-servers/slapd.conf.obsolete /etc/openldap/slapd.conf
cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG

4. slappasswd

打上欲設定的ldap server密碼，將最後一行{SSHA}xxxxxxxxx複製起來

5.編輯/etc/openldap/slapd.conf

把裡面的dc=my-domain,dc=com改成自己要的

在rootpw的地方把剛剛複製的{SSHA}xxxxx貼上去

6.建立一root.ldif檔，內容

#root

dn: dc=my-domain,dc=com

dc: my-domain

objectClass: dcObject

objectClass: organizationalUnit

ou: my-domain.com

7. 先把slapd.d裡的資料移除

rm -rf /etc/openldap/slapd.d/*

8. 使用slaptest將slpad.conf轉成slapd.d/

slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d

9. 改變檔案權限及擁有者

chown -R ldap:ldap /var/lib/ldap

chown -R ldap:ldap /etc/openldap/slapd.d

10.將slapd設為system boot up自動啟動

chkconfig slapd on

11.啟動slapd

service slapd start

12. 登入Webmin的LDAP Users and Groups (config要設好)

LDAP server uses encryption? -> Yes SSL

Bind to LDAP server as -> cn=Manager,dc=my-domain,dc=com

Credential for bind name above -> Set to "ldap server password"

13. Open port 389 TCP in firewall

nsupdate出現SERVFAIL

查看/var/log/message，因為權限的問題，所以
chown -R named:named /var/named
or
chown -R named:named /var/named/chroot/var/named
還有SELINUX預設也會擋，要關掉bind的部分 named_write_master_zones

setsebool -P named_write_master_zones 1

yum repo setting

若出現cannot find a valid baseurl for repo的訊息
請編輯/etc/yum.repo.d/裡面的.repo檔案
把baseurl前面的#去掉

1. Download ntlmaps
