OpenLdap数据库DB_CONFIG参数配置

进入/openldap2.3.43/var/openldap-data目录，vi文件DB_CONFIG

1.在openldap2.4.41版本下，DB_CONFIG为DB_CONFIG.example，且两个地方都有该配置文件。：

/home/openldap/openldap2.3.43/var/openldap-data/DB_CONFIG.example /home/openldap/openldap2.4.41/etc/openldap/DB_CONFIG.example

2.修改文件内容如下

# $OpenLDAP: pkg/ldap/servers/slapd/DB_CONFIG,v 1.1.2.4 2007/12/18 11:51:46 ghenry Exp $
# Example DB_CONFIG file for use with slapd(8) BDB/HDB databases.
