Servlet Specification describes a portable mechanism for applications to declare their security requirements (in the web.xml deployment descriptor). This is required in case of using a web application that includes one or more elements, and a element defining how users are required to authenticate themselves. RealmsĬonfigure Tomcat to support container managed security by connecting to an existing “database” of usernames, passwords, and user roles. NOTE: For a newly installed Tomcat 7 web server, the role and user entries were commented in the tomcat-users.xml.

roles – Comma-delimited list of the role names associated with this user.password – Password this user must log on with (in clear text).username – Username this user must log on with.Note that a user can have more than one role.

This has three required attributes: username, password and roles. The attribute rolename specifies the name. : Each role that a user can play is defined with a element. This has two nested elements: role and user. tomcat-users.xml is one of the configuration files.Īn example of the tomcat-users.xml file is shown below: The main configuration file is server.xml. Tomcat configuration files are found in the directory: CATALINA_HOME/conf (where CATALINA_HOME environment variable is the Tomcat installation directory).

Provides consistency over multiple applications.

Relieves the programmer to write security related code (though they can if they want to).

Also known as declarative security (for authentication and authorization).

Container Managed SecurityĬontainer managed security provides enforcing and implementing security policies on the web server. Tomcat uses realms to implement container-managed security and enforce specific security policies. This has the following information: username, password and the roles which are assigned to the users.īoth of the authentication and authorization make up the security policy of a server. A realm is a repository of user information it is an abstraction of the data store – text file, JDBC database or a JNDI resource.
