LogonUserA and Citrix

Hi all,

I have written a VB.NET application that use LogonUserA to authenticate user. It works fine when program running under WinXP.

When I move the program to Citrix server........firstly, SystemInformation.UserDomainName() always return local domain instead of the domain I logon to.

Secondly, even I hard-code the domain name to pass to the LogonUserA function, it always return authentication fail, just because it still check password to the local domain.

Anyone have idea on how to solve this problem?

Thx!!

I believe Citrix uses some of the terminal server functionality as it does have a requirement to run on a server with terminal server services installed and running. So perhaps a few of the terminal server API calls may help you.

WTSOpenServer, WTSEnumerateServers, WTSEnumerateProcesses etc.
