Cannot use windows authentication when connecting from citrix


I’m triyng to get a connection to NAV SQL from a Citrix environment to work.

When connecting from the LAN to a Citrix Web Interface I try to call this string

“C:\Program Files (x86)\Microsoft Dynamics NAV\CSIDE Client\finsql.exe” SERVERNAME=%My SQL server%, DATABASE=%My NAV DB name%, ntauthentication=1, nettype=TCP/IP Sockets, company=%My Company Name%

When I start the app, I get this error

18452,“28000”,[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user ". The user is not associated with a trusted SQL Server connection.

After I press OK, I can see in the logon box for NAV, that Servertype is selected “Microsoft SQL Server” and not “Microsoft Dynamics NAV Database” is this the correct configuration, and if so how do I change this ?

When connection to a CSG/WI server from the Internet to my company, the same applications are presented, and here I can succesfully connect to the published application.

The difference between the 2 WI servers are that one is in a DMZ and the other is a Domain member.

Hope you can help me out.
