There a URL ABC.com protected by siteminder and it's using windows auth scheme and the auth level is 5. Another URL XYZ.com protected by siteminder and it's using HTML form based auth scheme and auth level is 2. First i am accessing the ABC.com and challeged for credential and logged in successfully after provided the correct credential. Now i am opening new tab in the same browser and accessing XYZ.com and i am getting login page. It should not ask for credential as i have already logged into ABC.com which is using higher auth level than xyz.com. I would like to know why it's asking for credential?
