openldap学习笔记
其中理解可能也有不当之处,欢迎各位指正。
第一部分:openldap介绍
一、Directory Services(目录服务)能做什么?
我们知道,当局域网的规模变的越来越大时,为了方便主机管理,我们使用DHCP来实现IP地址、以太网地址、主机名和拓扑结构等的集中管理和统一分配。同样,如果一个局域网内有许多的其它资源时,如打印机、共享文件夹等等,为了方便的定位及查找它们,一种集中定位管理的方式或许是较好的选择,DNS和NIS都是用来实现类似管理的方法。
对于局域网内的一个用户来讲,工作等其它应用需要,我们必须凭帐号登录主机、用帐号收发E-mail,甚至为了管理需要公司还需要维护一个电子号码簿来存储员工的姓名、地址、电话号码等信息。随着时间的增长,我们会为这些越来越多的帐号和密码弄的头晕脑胀。同时,如果一个员工离开,管理员就不得不翻遍所有的记录帐号信息的文件把离职员工的信息删除。这些将是一个繁琐而效率低下的工作。那么,如果能将此些帐号信息等统一到一个文件中进行管理,无疑会大大提高员工及管理员的工作效率。目录服务(LDAP是其实现的一种)正是基于这些应用实现的。

[Exchange]OWA无法编辑邮件的问题
SYMPTOMS
Symptom 1
On a computer that is running Microsoft Windows Vista, you cannot perform any editing tasks that you typically expect to perform. For example, you cannot perform the following tasks:
• | Compose a new e-mail message |
• | Reply to an e-mail message |
• | Create a new contact, task, note, journal entry, or appointment |
• | Change any configuration in the Outlook Web Access options folder Additionally, you may receive an error message when you try to perform these tasks. |
On a computer on which you have installed update 912945, you must first click one time in the compose frame in Outlook Web Access before you edit text. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
CAUSE
This behavior occurs because Windows Vista no longer includes support for the ActiveX control that is used for HTML editing in Outlook Web Access.
Symptom 2
Update 912945 requires that you click one time in an ActiveX control to enable the control in Internet Explorer 6.
Symptom 3
Security update 912812 requires that you click one time in an ActiveX control to enable the control in Internet Explorer 6.
RESOLUTION
Important For this resolution to work, you must apply the hotfix to both the front-end server and to the back-end server

如何在Firefox中强制重画页面
How to force firefox redraw ( admin.net [at] 163.com)
Firefox中,有时会发现使用JS改变了一些表格的宽度或页面,但Firefox并没有重画,手动调整一下窗口大小后才正常。
可以使用下面的代码,让Firefox强制重画网页:
var objTemp=document.firstChild;
if (objTemp)
{
//Tom Zhou (admin.net[at]163.com
objTemp.style.width = objTemp.offsetWidth - 1;
objTemp.style.width = objTemp.offsetWidth + 1;
}

NetLimiter
NetLimiter是一款运行在Windows 98/98SE/Me/2000/XP/2003/Vista上的网络流量控制软件。
通过它,您可以直接来控制每个程序对Internet的访问以及流量分配情况。例如,您可以用NetLimiter来为单个程序甚至是单个网络连接限定其上载和下载速度。通过非常简单的设置,NetLimiter就可以让你随心所欲地在各个程序之间分配网络带宽。
随着宽频网络的日益普及,使用P2P类下载软件(如:BT、迅雷、eDonkey、eMule..等等)的人越来越多,但是在使用此类软件时,通常会因他们的高速而「榨干」了我们有限的带宽,其他需要透过网络来联机的应用程序就几乎动弹不得了!有时想一边下载一边浏览网页都不行,蜗牛般的页面打开速度和极高速的文件下载速度总是让电脑使用者在一旁哭笑不得...
NetLimiter它不仅可以控制某个应用程序的上传/下载使用带宽,还可以实时监控所其占用的带宽,甚至于,你可以限制你的电脑的总上传/下载带宽!网络速度分配完全随心所欲。不仅可以让你随心的分配有限的网络带宽,他还能帮你楸出占用你大量带宽的元凶呢~(例如某些木马、间谍程序、流氓软件、病毒等等),现在你可以通过他完全掌握你的网络传输情况了~
