Fedora 4 uses servlet container authentication (Realms) to provide minimal protection for your repository with a master "superuser" user and password. The superuser credentials are configured in your web application container's properties file; once configured, all management (write) operations will require authentication. This document describes how to set up Fedora to enable HTTP Basic Authentication.
The superuser property name superuserrole is fedoraAdmin. This is comparable to the fedoraAdmin superuser role in Fedora 3, used for Fedora 3 API-M operations.
Configure your repo.xml file
Add the beans authenticationProvider and pep to your repo.xml , file, and make the modeshapeRepofactory bean dependent on authenticationProvider. Use the class org.fcrepo.auth.ServletContainerAuthenticationProvider as your authentication provider. Here is an example repo.xml that configures authentication and authorization using the Basic Roles PEP:
Code Block language xml title repo.xml with authentication configured <bean name="modeshapeRepofactory" class="org.fcrepo.kernel.spring.ModeShapeRepositoryFactoryBean" p:repositoryConfiguration="${fcrepo.modeshape.configuration:classpath:/config/rest-sessions/repository.json}" depends-on="authenticationProvider"/> <bean name="pep" class="org.fcrepo.auth.roles.basic.BasicRolesPEP"/> <bean name="authenticationProvider" class="org.fcrepo.auth.ServletContainerAuthenticationProvider"> <property name="pep" ref="pep"/> </bean>
Configure your repository.json file
Add or modify the security section to enable an authenticated internal session between Fedora and ModeShape. It should match this block:
Code Block language ruby title repository.json security "security" : { "anonymous" : { "roles" : ["readonly","readwrite","admin"], "useOnFailedLogin" : false }, "providers" : [ { "classname" : "org.fcrepo.auth.ServletContainerAuthenticationProvider" } ] },
Configure your web application container
Jetty
Create your jetty-users.properties file. This file contains entries in the format username: password [, role, ...], where
- username is the user's login id (the principal)
- password is the user's password
- role is the servlet role they are assigned upon login; jetty allows you to specify any number of roles (or no role at all). Fedora currently supports two roles: fedoraAdmin, which is the superuser role, and has rights to do everything; and fedoraUser, which is a user role, and must be granted permissions to perform actions.
Sample jetty-users.properties file that contains three users, two of whom are regular users, and the third of whom (fedoraAdmin) is a Fedora superuser:
Code Block title jetty-users.properties testuser: password1,fedoraUser adminuser: password2,fedoraUser fedoraAdmin: secret3,fedoraAdmin
- Configure your Jetty login realm.
Standalone
Modify your jetty.xml file to configure the login realm and include the jetty-users.properties file:Code Block language xml title jetty.xml login service <Configure class="org.eclipse.jetty.webapp.WebAppContext"> <!-- Set this to the webapp root of your Fedora 4 repository --> <Set name="contextPath">/</Set> <!-- Set this to the path of of fcrepo4 WAR file --> <Set name="war"><SystemProperty name="jetty.home" default="."/>/webapps/fcrepo4</Set> <Get name="securityHandler"> <Set name="loginService"> <New class="org.eclipse.jetty.security.HashLoginService"> <Set name="name">fcrepo4</Set> <!-- Set this to the path to your jetty-users.properties file --> <Set name="config"><SystemProperty name="jetty.home" default="."/>/path/to/jetty-users.properties</Set> </New> </Set> </Get> </Configure>
Fedora4 uses the org.eclipse.jetty.security.HashLoginService
Jetty login service.
See the Jetty Authentication documentation for more details.
