IBM Cognos reports are requiring a USER NAME when connected to TM1

Hello All, We have IBM Cognos connected to TM1 using an integrated login, however, when running a report, it asks for the user name and password. If we enter the USER NAME ONLY, then the report will run fine. If anything else, then the report will not run. The COGNOS web site recognized me, because the IBM Cognos(https://goo.gl/T6BtJG) requires no login prompt and it displays my name at the top of the screen. How can I get it to run the report and use the Integrated logon and not require me to enter my user name? The Cognos version i s 10.1.1 and the TM1 version is 9.5.2 Thanks
