Hi,

I want to validate Users in the Windows SAM through
a Visual Basic 6 application.

Here is the requirement:

1. Post a Logon Dialog Box (Username, Password, Domain) in a VB6 Form
2. Test the Information entered against a valid windows user account

Return True if the User Exists and the Password is correct.
Return False if the information supplied is incorrect.

If True - What Group is the User a Member of

Essentially, we want to use the windows user manager to manage users
and test these against these accounts in the SAM without having to
actually log a user into or out of Windows for in application
security.

Please Help if you can - Example Code would be greatly appreciated.
Otherwise, if anyone knows of an ActiveX control to do this that would
work as well.

Thank you and Best Regards

Is this an NT or Active Directory domain?

We are using Windows 2000 and Windows XP in 2 flavours

In basic systems, we use Win2K Professional as a workgroup, and in more
advanced systems, we use Win2K server with either a workgroup or active
directory domain.

I was looking at SSPI or Win32 API LogonUser()

Please Advise.

Thanks

For domain authentication you should be able to use ADSI (Reference is Active DS Type Library):
