Issue while login to BI4.1 SP5 IDT with windows AD authentication type .

Hello SAPBO/BI4.1 experts ,

I have installed BI4.1 SP5 complete suite and when i try to log into Information Design Tool with windows AD authentication,getting the below error ,

But with other authentication types like SAP and Enterprise its working fine .

Please note that i have been tried with Username@DNS_DomainName ,but no luck and its not working .

Please let me know with detail steps as solution ,

Thanks a lot in advance ,
