Hello Nazrul,
This issue can be caused by different factors. Please take a look to the following forum threads where this topic has being discussed:
http://www.sitefinity.com/developer-network/forums/bugs-issues-/enabling-role-provider-causes-exception
http://www.sitefinity.com/developer-network/forums/bugs-issues-/sf-4-4-to-5-0-upgrade-error/page/2
Another possible reason for this issue could be if you are using Cassini server.
Also please check if you have some custom logic running on the backgroud that is trying to authenticate for example a scheduled task, service call or a custom module. If you do try to disable it and see if the issue will continue.
