"Action not authorized" error thrown when checking out a kb article articleIssue Users have correct user criteria at the KB level and the article level but are presented with an "Action not authorized" error when checking out the article. ReleaseAllCauseArticle version is a different domain than the user trying to check it out.Resolution1. The reason for this behavior could be, even though the article (kb_knowledge) is in the "X" domain, the knowledge versions (kb_version) are in the "Y" domain. 2. The user who published the latest version, belongs to "Y" hence the version was created in the same "Y" domain.3. Now, since user trying to check the article belongs to "X" domain and does not have access to the "Y" domain, he/she won't be able to edit the article and will be thrown the "Action not authorized" error. 4. Only a user with access to this "Y" domain will be able to check it out.
