Subject: RE: [ActiveDir] AD in .NET Visual Basic
Hello Marc,
Welcome to the world of System.DirectoryServices. Could you please post the extended error to the list?
Just a few things,
1. You should specify
a search filter for your query, this will limit the amount of time it takes for
your query return results. An example to specify the search query =
mysearcher.Filter =
"(&(objectCategory=user)(objectCategory=person))"
2. It is best practice to actually load the required properties into the search, you can load them one by one or you can load a property array. For example loading 1 by 1 = mysearcher.PropertiesToLoad.Add("cn") or an array = mysearcher.PropertiesToLoad.AddRange(MYSTRINGARRAY)
3. Also as a good practice instead of doin result.findall at the
loop level rather try this
Dim results As
SearchResultCollection
Dim result As SearchResult
results = mysearcher.FindAll
Then in your loop try
For Each result In results
If
result.Properties.Contains("cn") Then
'do something with result
End
If
Next
The reason you should use .Contains is because if the property does not contain a value you will receive and error = Object not set to an instance...
As a test could you specify a username , password and authentication type in the directoryentry.
For example
Dim entry As New
DirectoryServices.DirectoryEntry("LDAP://ou=tele_dom
users,DC=PROD,DC=TELENET,DC=BE",<USERNAME>,<PASSWORD>,AUTHENTICATIONTYPE)
This is just to perform a test we can change this later.
Let us know about the extended error. You have obviously checked that the LDAP path is correct (sorry but I have to ask: P)

DirectoryServices.DirectoryEntry("LDAP://ou=tele_dom

Dim mySearcher As New
System.DirectoryServices.DirectorySearcher(entry)
Dim result As
System.DirectoryServices.SearchResult
Dim oValue As New
ArrayList

Each result In mySearcher.FindAll()
oValue.Add(Microsoft.VisualBasic.Right(result.GetDirectoryEntry().Name,l
