红帽全球峰会第 15 章 禁用匿名绑定
如果用户尝试连接 Directory 服务器而不提供任何凭证，则此操作被称为 anonymous bind。匿名绑定简化了搜索和读取操作，如在目录中查找电话号码，而无需用户首先进行身份验证。但是，匿名绑定也可能会造成安全隐患，因为没有帐户的用户可以访问数据。
警告
默认情况下，在 Directory 服务器中启用了匿名绑定来搜索和读取操作。这允许未授权访问用户条目以及配置条目，如根目录服务器条目(DSE)。
15.1. 使用命令行禁用匿名绑定

将
nsslapd-allow-anonymous-access配置参数设置为off：# dsconf -D "cn=Directory Manager" ldap://server.example.com config replace nsslapd-allow-anonymous-access=off
验证
运行搜索但不指定用户帐户：
# ldapsearch -H ldap://server.example.com -b "dc=example,dc=com" -x ldap_bind: Inappropriate authentication (48) additional info: Anonymous access is not allowed
