Enter LDAP Password:
ldap_bind: Invalid credentials (49)

fedora系统，但是运行ldapadd，ldapsearch等任何命令都会出现上面显示的错误，我的slapd.conf配置信息如下，位置在/usr/local/etc/openldap/slapd.conf，各位高手请帮帮忙，小女子不胜感激。

我网上查了很多相关信息，但都没什么建设性意见

因为fedora系统自带了一个LDAP，但仅有ldap.conf的配置档，却没有slapd.conf服务器这个重要的conf档，所以我就下了一个openldap，自己安装了下，不知道是不是因为两者冲突造成的（我试图将自带的那个卸载掉，一直不成功，有很多关联）

领导布置的任务，要求将mail server与LDAP结合，但我这LDAP server捣腾好多天了，还是没能成功，眼看指定日期快到了，还望各位帮帮忙，非常非常感激。
