Active Directory authentication/group membership check with MSAccess 2007 VBA
I'm unfortunately responsible for maintaining some old interfaces written in VBA through MS Access. Currently I'm migrating these over to a new server and one of the things I want to do is improve the login system for these interfaces by integrating them with Active Directory. It's pretty simple: All I need to do is (a) check to make sure the provided username/password combination are correct, and if so, (b) check to see if the user is in a specific Active Directory group.
Any ideas on how to go about doing this? I had written a library in .NET that these interfaces were using on the old server, but on the new server it's not working properly. If there's some way that I can pretty easily and effectively do it right through VBA, I'd prefer that over having to troubleshoot this library that I wrote.
EDIT: I should add, I've been playing around with ADODB to make the connection. It seems to work and I can look up AD object properties but I'm not sure what the best way is to check the username/password.
