Apache Tomcat 9 unable to access manager webapp

Question

I successfully install Apache Tomcat 9 and I access at servername:8080.

I follow documentation in order to access the manager web app and :

• open $CATALINA_HOME/conf/tomcat-user.xml
• add <role rolename="manager-gui"/>
• add <user username="tomcat" password="s3cret" roles="manager-gui"/>
• $CATALINA_HOME/bin/catalina.sh stop
• check servername:8080 is down
• $CATALINA_HOME/bin/catalina.sh start
• check servername:8080 is up
• servername:8080/manager/html return HTTP Status 403 – Forbidden

I can't find what config I am missing and will be greateful for any kind of help or suggestion.
