400 response with json/users endpoint in AM (All versions) if username contains forward slash
The purpose of this article is to provide assistance if you receive a 400 Bad Request response when the username contains a URL encoded forward slash (%2F) and you make a REST call to the json/users endpoint. You will see a 404 Not Found response instead if the forward slash is not encoded. This issue only occurs if AM is deployed in the Apache Tomcat™ web application container.
