VB.NET Return Active Directory UserNames

[Atreyu 0]

Using VB.NET...

 

I created a program that randomly generates usernames. Now I need it to search the Active Directory to ensure the username does not already exist. How would I search my Active Directory to return a matching username? Also, how would I query Active Directory to return a listing of all usernames? This was easy in VB6... but doesn't seem to be as straight-forward now.

 

Thanks in advance.

Are you using Server 2003?

It shouldn't matter, but yes... it's on a couple servers (mixed with 2k).

 

Either way, I figured it out. I'll post the code when I get off of work.

I misunderstood the questions.

 

 

I thought you were trying to query AD for specific users.

 

 

With Server 2003 you can use DSGET command

 

 

But since you are talking programming, thats not my thing

No problem. Here's what I found to work. It returns the user's name, their path, and also their alias (or username).

 

Code:

        Dim enTry As DirectoryEntry = New DirectoryEntry("LDAP://mydomain")        ''Console.Write(enTry.Username)        Dim mySearcher As DirectorySearcher = New DirectorySearcher(enTry)        mySearcher.Filter = "(objectClass=User)"        Dim resEnt As SearchResult        For Each resEnt In mySearcher.FindAll()            Console.WriteLine(resEnt.GetDirectoryEntry().Name.ToString())            Console.WriteLine(resEnt.GetDirectoryEntry().Properties("sAMAccountName").Value.ToString())            Console.WriteLine(resEnt.GetDirectoryEntry().Path.ToString())            Console.WriteLine(resEnt.GetDirectoryEntry().NativeGuid.ToString())            Console.WriteLine("===========================================")        Next
