SSO using user ID and password

Hi ,

I have installed EP 6.0 SP2 running on SQL DB,Business Package for ESS for SAP R3 4.7 , ITS6.20.

Portal is runing fine and i also have set up the SSO with R3 using UIDPWD. I can able to access ESS iviews. Everything runs fine.

But the problem is that after accessing 6/7 iviews of ESS, i am prompted for User id and Password. ( Welcome screen is displayed). I have checked the no of session in SAP R/3 ( Transaction : SM04) there are 4/5 RFC session found.

Please do let me know if any other information i have missed out. Any idea always appriciated.

Regards
