VB.NET的LDAP查询问题 [英] LDAP query problem with VB.NET

问题描述

我正在运行一小段代码，用于填充LDAP查询的下拉列表。它检查给定名称或姓氏是否以输入的字母开头。例如



S会返回sarah或smith

SM只会返回史密斯



但不是如果职位名称=离开者



代码工作正常，除非我想在查询中添加不是



这个有用： -

I'm running a small piece of code that populates a drop down from an LDAP query. It checks if the givenname OR the surname start with the letter that is input. e.g.

S would return sarah or smith
SM would return just smith

but not if the Job title = leaver

The code works fine, except if I want to add a not to the query

This works :-

osearcher.Filter = "(|(givenname=" & Label1.Text.ToString & "*)(sn=" & Label1.Text.ToString & "*))"

但这不是： -

But this doesn't :-

osearcher.Filter = "(|(givenname=" & Label1.Text.ToString & "*)(sn=" & Label1.Text.ToString & "*))(!(title=leaver))"

我收到目录服务不可用错误



有什么想法吗？我只使用LDAP作业标题字段来排除某个OU



我尝试了什么：



我将查询剪切并粘贴到活动目录自定义搜索中并且工作正常



（例如，结果看起来像这样

I get a "The Directory Service is unavailable" error

Any ideas ? I'm only using the LDAP Job Title field to exclude a certain OU

What I have tried:

I cut and pasted the query into an active directory custom search and it worked fine

(e.g. the result looks like this

(|(givenName=a*)(sn=a*))(!(title=leaver))

推荐答案

就像我提交的那样我修好了它。



好​​像用vb.net你需要用&符号开始查询，例如

Ugh just as I submitted I fixed it :)

Seems like with vb.net you need to start the query with an ampersand e.g.

osearcher.Filter = "(&(|(givenname=" & Label1.Text.ToString & "*)(sn=" & Label1.Text.ToString & "*))(!(title=leaver)))"
