Hi Christof,

I don't have access to the article because I'm not a subscriber to the magazine. However, I downloaded the code and I see a lot of similar things I've seen before and tested but nothing related to a work around for this issue in VFP6.

I need this to work to be able to call .OpenDSObject for user authentication. Is there a work around that I missed?

The other option I tried was the LogonUser API but it always returns 0 when connecting via Citrix.
