Thank's for your response!
I'm using section acces, however i can not imagine how osuser() will help me at this point.
By default the AccessPoint prints the users LoginName which is used for the ticketlogin at the custom loginpage
Can you describe me that in a greater detail? May i dont get you.
I have to say that the AccessPoints are not members of the AD-Domain. So i have to provide the DisplayName in a different manner. (maybe in the ticketrequest xml?) - (A ActiveDirectory-Service-Connector is working on the QlikViewServer)
