症状

When using the User List Macro, the error: "User list not rendered as you do not have the privilege to view user profiles." is displayed

原因

This error is only displayed if you have disabled the People Directory using the -Dconfluence.disable.peopledirectory.all=true  or -Dconfluence.disable.peopledirectory.anonymous=true  flags in JAVA_OPTS variable

ソリューション

User List functionality is disabled because it functionally gives anyone who can edit/comment/use a macro the ability to list out arbitrary groups of people in Confluence, including their online status and email address.
