I have a SharePoint 2013 anonymous site.If I add a user to any group then those users are added to User Information List but new users when they log in to the site (who are not given explicit permission through any groups) are not being automatically added to User Information List. Any help to investigate this is highly appreciated.
Edit: The user profile is configured and working.I have another web application in the same farm which automatically adds new users to User Information List once they log in.
Everyone group will be added to User Information List by default for all anonymous sites. Somehow in this faulty site where I had this issue Everyone group was not added to User information list by default. So I added Everyone group to the site user information list then things started working.To add everyone group to user information list, you just need to add it to any SP group and later remove it.
