LDAP 用户更改自己的密码
LDAP中采用了ACL的权限控制。
在/etc/openldap/slapd.conf文件中：
#
# See slapd.conf(5) for details on configuration options.
# This file should NOT be world readable.
#

include /etc/openldap/schema/core.schema
include /etc/openldap/schema/cosine.schema

# 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
#下面的控制权限的语句。
access to dn.subtree="ou=People,dc=bawo,dc=cn" attrs=userPassword,shadowLastChange
by dn="cn=admin,dc=bawo,dc=cn" write
by self write
by anonymous auth
by * read
#access to attrs=uid,uidNumber,gidNumber,memberUid
# by * read
# 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)
database config
access to *
by dn.exact="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" manage
by * none
# enable server status monitoring (cn=monitor)
database monitor
access to *
by dn.exact="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" read

# Cleartext passwords, especially for the rootdn, should

# Use of strong authentication encouraged.

# Indices to maintain for this database
index objectClass eq,pres
index ou,cn,mail,surname,givenname eq,pres,sub
index uidNumber,gidNumber,loginShell eq,pres
index uid,memberUid eq,pres,sub
index nisMapName,nisMapEntry eq,pres,sub
添加完上面的语句后，然后需要更新这个配置文件到ldap的服务中。
service slapd stop rm -rf /etc/openldap/slapd.d/ chown -R ldap:ldap /var/lib/ldap chown -R ldap:ldap /etc/openldap/ #测试并生成配置文件： slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d #返回config file testing succeeded,则配置成功。 chown -R ldap:ldap /etc/openldap/slapd.d service slapd restart
完成之后，就把LDAP的权限设置成功了。用户可以在phpLDAPadmin中自行修改自己的密码了。
其他设置项目可以自行探索。
