Hi,

I am using AD and FBA authentication using Default Zone.While click sign in as different user,it will always take me into the account which i first logged in..I cant guess where its going wrong.Can anyone suggest me the solution for this issue.

Hi,

It seems the Session variables contain information from previous user as the cookies are not cleared.

Here is a blog for your reference:

You can also customize a feature to achieve the same function, clean the session and cookies, then redirect to the login page.
