InfoPath 2007 - browser enabled webservice call - Error occurred accessing a datasource

[joris]

I created an InfoPath 2007 form which accesses a webservice (which in turn
retrieves data from AD) - the form works correctly when opening it from within
the InfoPath 2007 client application but when I publish it to InfoPath Forms
Services it gives an error stating and I try to fill in a new form (With
advanced settings > open in web page). If I use "open in the client application"
it works...

"There has been an error while processing the form. An error occurred accessing
a data source. An entry has been added to the Windows Event Log of the Server.
LogID 5569".

But when I check the eventlog I don't see any error logged. Does anybody
know what is the problem. Do you need to do extra things when using a webservice
as a datasource in a web-enabled InfoPath form,

Hey Joris,
Sounds like a security issue between your web service and the form running
in the web browser, have you tried setting your web services to have
anonymous access?
