1、修改slapd.conf配置文件

# The next three lines allow use of TLS for encrypting connections using a

# Sample security restrictions
# Require integrity protection (prevent hijacking)
# Require 112-bit (3DES or better) encryption for updates
# Require 63-bit encryption for simple bind
# security ssf=1 update_ssf=112 simple_bind=64
# Sample access control policy:
# Root DSE: allow anyone to read it
# Subschema (sub)entry DSE: allow anyone to read it
# Other DSEs:
# Allow self write access
# Allow authenticated users read access
# Allow anonymous users to authenticate
# Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *
# by self write
# by users read
# by anonymous auth
#
# if no access controls are present, the default policy
# allows anyone and everyone to read anything but restricts
# updates to rootdn. (e.g., "access to * by * read")
#
# rootdn can always read and write EVERYTHING!
# enable on-the-fly configuration (cn=config)

2、生成DB_CONFIG
updatedb
locate DB_CONFIG.example
cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/
3、插入对象top，不然连接后会显示无效独享
vim db.ldif
dn: dc=freind,dc=com
dc: freind
objectClass: top
objectClass: domain
4、建立DB
slapadd -f slapd.conf -l db.ldif -F /var/lib/ldap
5、测试配置
slaptest -f slapd.conf -F /etc/openldap/slapd.d/
chown -R ldap:ldap /var/lib/ldap
6、启动ldap
service slapd start
或
slapd -d1 打印启动过程
7、ACL
限制查看权限
access to attrs=userPassword
by self write
by anonymous auth
by dn.base="cn=Manager,dc=test,dc=com" write
by * none
access to dn.base="ou=People,dc=test,dc=com"
by self write
by dn.base="cn=Manager,dc=test,dc=com" write
by * read
access to *
by self write
by dn.base="cn=Manager,dc=test,dc=com" write
by * none
