ACLs are not honored in search page in portal for knowledge articles.Issue The customer had created ACL which would prevent the user from viewing the knowledge article when it is opened. However, the ACL does not apply to the search page, meaning, that when a user searches for an article that they do not have access to, it will appear on the search page. When the user tries to open it, they would see 'insufficient privilege'.ReleaseService portalCauseThe cause of the issue is the system property "glide.knowman.search.apply_acls". This is set to false by default and the ACLs are not applied in portal search.ResolutionOnce the system property "glide.knowman.search.apply_acls" is set to true, the articles don't show up for the user in search as well, as ACLs are honored.
