Active Directory Searching with ASP.Net
Whenever I’ve Googled for and Visual Basic or C# code which will allow me to search through Active Directory I’ve had no luck. So, I wrote my own.
There are 2 parts to this project:
- A User Class which defines all of the properties related to AD.
- An Active Directory class which searches AD and creates an collection list made up of user objects which can then be bound to a Gridview or used as an object elsewhere.
There a number of functions in my Active Directory class such as find users by Groups, list all users in an AD group, select a single user from the list, etc. It could quite easily be expanded to meet your needs.
Below is a screen shot where I have implemented a Web Page which just allows for basic searching. You choose the AD property you want to search against and the results are displayed in a Gridview.

UPDATE: I missed out the ‘directReports’ property in Active Directory. To make use of this you need to add a new collection to the User class and populate it with a user objects.
e.g.
In User Class:
private _directReports as collection
public property directReports as collection
get
return _directReports
end get
set (byVal value as collection)
_directReports = value
end set
end property
In AD Class: (In the same way as groups work)
For index as integer 0 to oResults.properties("directReports").count - 1
dim staff as new user
staff.username = extractName(oResults.properties("directReports").item(index))
oUser.directReports.add(staff)
next

Thenx Bro Thanke u sooooooooo much
is there any way to get the user password…
I read similar article also named e Directory Searching with ASP.Net, and it was completely different. Personally, I agree with you more, because this article makes a little bit more sense for me

Sorry for the late reply. I’ve been on holiday.
I presume that if you wanted to get user password then you just need to find out what the LDAP property is.
Then you would need to create a new Public Property for User.vb and add the following to AD.vb.
search.PropertiesToLoad.Add("PASSWORD_PROPERTY")I strongly suspect that you will find that passwords are encrypted though.
Pretty nice site, wants to see much more on it! :)t
Excellent Nick.
I have downloaded the above code. How do I create a connection to an Active Directory server?
I know we need to create DirectoryEntry(”LDAP://…”). Any ideas on how to do this and where to have this in the code?
Just want to test this on a live active directory.

Thanks for the comments. On my network the code just connects automatically to Active Directory so just try it and see. The only reason you would need to introduce a connection string would be if you want to use a Proxy Account to access AD.
