Access Required: Let us know why you need access to this site.

Mar 9, 2016 at 11:54 AM
Running the solution on SharePoint 2013. The page to change password works but I want to restrict the access to the site collection as it is access from internet and used by various parties.

On the site collection root site I have removed any general "everyone" or "authenticated users" groups access. This results in getting the access required page before allowing the user to access the /_layouts/15/ChangePassword/Changepassword.aspx page.

I have done some troubleshooting and come to the following conclusion:
  • Make sure to change Permissions Levels at the root site collection and allow "View Application Pages - View forms, views, and application pages. Enumerate lists. " and "View Pages - View pages in a Web site. " permission.
  • Create new sharepoint group at collection level and assign the new permission level you created above.
  • Add everyone to the group
Basically this solved my issue to allow external users outside my AD to change their password. Make sure that password is not expiring as this won't allow them to logon through TMG server (in my case).
