CentOS 6配置LDAP允许用户自行修改密码

在LDAP中,默认情况下用户无权修改自己的密码,如果用户自行修改密码,会遇到Result: Insufficient access (50)的错误,因此我们需要打开用户修改自己密码的权限。本文基于CentOS 6。

vim /etc/openldap/slapd.conf

修改配置文件,在database config前添加如下内容(注意格式!)

access to attrs=userPassword
	by self write
	by anonymous auth
	by * none

access to * by * read

by self write表示允许登陆用户修改自己的userPassword属性;
by anonymous auth允许匿名用户(即non-authenticated用户)基于验证目的访问userPassword,而不是其它目的(例如搜索和读取等)
by * none是阻止所有用户访问该用户的userPassword属性


Table 5.3: Access Entity Specifiers
Specifier Entities
* All, including anonymous and authenticated users
anonymous Anonymous (non-authenticated) users
users Authenticated users
self User associated with target entry
dn[.<basic-style>]=<regex> Users matching a regular expression
dn.<scope-style>=<DN> Users within scope of a DN


$ rm -fr /etc/openldap/slapd.d/*
$ slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d
#测试配置文件语法是否有错误,如果提示testing succeeded则可以进入下一步
$ chown -R ldap:ldap /etc/openldap/slapd.d/
$ /etc/init.d/slapd restart
