UserID and password authentication

[Jonathan]

Hello

I'm writing a VB 6.0 application on a WinXP client. Servers run Win2K. Is
there a way to take a network-logon UserID and password and authenticate it
against active directory? I would like the uses to enter the same UserID and
password for the app as they do to log in to WinXP



Thanks

Jonathan

I know of an API to get the User ID, but not the password.

Private Declare Function GetUserName Lib "advapi32.dll" Alias
"GetUserNameA" _
(ByVal lpBuffer As String, _
nSize As Long) As Long

Function NetUserName() As String

Dim lNameLen As Long
Dim rc As Long

Dim sUserName As String
sUserName = String$(254, 0)
lNameLen = 255

rc = GetUserName(sUserName, lNameLen)

If rc > 0 Then
NetUserName = Left$(sUserName, lNameLen - 1)
Else
NetUserName = vbNullString
End If

End Function

There is no API to get the password since it's not stored anywhere - only a
"digest" of the password. It's those digests that are compared, not the
original text as entered by the user

As far as the account name itself goes, I'd recommend using GetUserNameEx
rather than GetUserName since it returns the full account name, including
any domain name, and so avoids accidental matching of similar names

Hi Paul
This is exactly waht I wanted and it works perfectly. I knew it had to exist
somewhere.

Thanks
