Active Directory Authentication
I need to do authentication via Active Directory.The VB6 program should only allow user to log in to the system if and only if user has key in correctly his AD login (samAccountName) and password.
However, i only manage to do authentication with samAccountName only. I find no way to check if user has key in correctly their password.
My Code is as below:
Does anyone has idea on how to do Active Directory authentication with samAccountName and password?
On Error Resume Next
Dim conLDAP As ADODB.Connection
Dim strSQL As String
Dim strLDAPConn As String
Dim rsUser As ADODB.Recordset
Set conLDAP = New ADODB.Connection
Dim strUserName As String
Dim strPassword As String
Dim a As String
strUserName = "USerId"
strPassword = "PASSWORD"
conLDAP.Provider = "ADSDSOOBject"
strSQL = "Select AdsPath,samAccountName, employeeID, Name, cn From 'LDAP://XXX.ad.ZZZZZ.com" _
& "' where objectClass='user'" _
& " and objectcategory='person' and" _
& " SamAccountName='" & strUserName & "'"
'open connection + password
'conLDAP.Open "DS Query", strUserName, strPassword
conLDAP.Open "Data Source=Active Directory Provider;Provider=ADsDSOObject"
'execute LDAP query
Set rsUser = conLDAP.Execute(strSQL)
'rs will be empty if authentication fail
If Err.Number = 0 Then
If Not (rsUser Is Nothing) Then
If Not (rsUser.EOF And rsUser.BOF) Then
a = rsUser("AdsPath")
a = rsUser("Name")
a = rsUser("employeeID")
a = rsUser("samAccountName")
a = rsUser("cn")
ElseIf Err.Number = -2147217865 Then
MsgBox "Error in LDAP settings" & vbCrLf & "Call Admin"
