When I enabled anonymous access, both user_A and user_B can access a page (page_1). After that, I put user_A into a group (group_X) which group_X do not have access to page_1. When user_A access page_1 again, it shows "Sorry, this site hasn't been shared with you." (Seems alright)
Then I remove user_A from group_X and i suspect that user_A can access page_1 again same as user_B. However, user_A no longer carry an anonymous identity, and unable to access page_1.
I tried to delete user_A's profile from "Manage User Profiles" in Central Administration but it will re-create itself when it log-in again. While user_B 's profile never exist in both db nor Central Administration.
May I ask if there is any script or procedure to reset user_A back to a real anonymous account same as user_B?
Thank you very much!
