Connect Design Studio to SAP BI Plataform

Hi,

I am trying to connect to a SAP BI plataform with Design Studio.

I followed SCN issue

https://scn.sap.com/thread/3577248

and all seems to be all right. I got a logon with the authentication data but in my logon i get not the authentication mode "Enterprise"

The field is grey and filled with no text.

How can i activate Authetication Enterprise??

Thank you and best regards
