Hi Yan,
As discussed,i have checked all scenarios which you mentioned in mail,let me explain one by one
1.Its not redirecting to any security page particularly,the scenario is when i login with admin user it enters into home page without any issue and once i logout and tried to login as a submitter then the page appears in front.The issue occurs only when i click any link in admin Home page,that means just login as admin,logout without clicking any link,again login as a submitter doesn't create any issue,the issue occurs only when the page redirect from admin home page.
2.I am able to open the Forms Home page with the link http://localhost:89/forms/Home/Task.
3.I tried with other browsers also like mozilla, IE ,the issue remains same.
4.After clear web browser's cache and cookies, issue occurs.
