This issue can occur if the User Profile Application (UPA) is out of sync. If a user profile and the relevant group memberships for the user are not synchronized, SharePoint Server 2013 may incorrectly deny access to a given resource.
To resolve this issue ensure the User Profile Service Application (UPA) is properly configured and fully synchronized with user and group memberships.
