When our users post surrveys using the forms data feature (in swedish: forumlärdata) it's not the logged in user name that is saved in the database. It seems to be some random user name that is saved. Different user name every time, but never the logged in user. 

What can be the problem?

How can I debugg this feature? Is this functionality built in deep in the Episerver code or can I some how put a breakpoint in the code and see what happends when I submit to the database?

Regards!
