The superuser role is fedoraAdmin.  This is comparable to the fedoraAdmin superuser role in Fedora 3, used for Fedora 3 API-M operations.

1. Configure your repo.xml file

   Add the beans authenticationProvider and pep fad 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 PEPauthorization delegate:

   Code Block
   language xml title repo.xml with authentication configured
   <?xml version="1.0" <bean name="modeshapeRepofactoryencoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" classxmlns:context="org.fcrepo.kernel.spring.ModeShapeRepositoryFactoryBean"http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd"> <!-- Context that supports the actual ModeShape JCR itself --> <context:annotation-config/> <bean name="modeshapeRepofactory" class="org.fcrepo.kernel.impl.spring.ModeShapeRepositoryFactoryBean" p:repositoryConfiguration="${fcrepo.modeshape.configuration:classpath:/config/restservlet-sessionsauth/repository.json}" depends-on="authenticationProvider"/> <bean class="org.modeshape.jcr.JcrRepositoryFactory"/> <!-- Optional PrincipalProvider that will inspect the request header, "some-header", for user role values --> <bean name="headerProvider" class="org.fcrepo.auth.common.HttpHeaderPrincipalProvider"> <property name="headerName" value="some-header"/> <property name="separator" value=","/> </bean> <util:set id="principalProviderSet"> <ref bean="headerProvider"/> </util:set> <bean name="pepfad" class="org.fcrepo.auth.roles.basic.BasicRolesPEPBasicRolesAuthorizationDelegate"/> <bean name="authenticationProvider" class="org.fcrepo.auth.common.ServletContainerAuthenticationProvider"> <property name="fad" ref="fad"/> <property name="pepprincipalProviders" ref="pepprincipalProviderSet"/> </bean> <!-- For the time being, load annotation config here too --> </bean> <bean class="org.fcrepo.metrics.MetricsConfig"/> </beans>

2. Configure your repository.json file

   Modify the security section to enable both authenticated (via authentication provider) and internal sessions 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.common.ServletContainerAuthenticationProvider" } ] },

3. Configure your web.xml

   Configure your web.xml.
   

   Modify fcrepo-webapp/src/main/webapp/WEB-INF/web.xml by uncommenting the security configuration

   Code Block

   <!--Uncomment section below to enable Basic-Authentication--> <security-constraint> <web-resource-collection> <web-resource-name>Fedora4</web-resource-name> <url-pattern>/*</url-pattern> <http-method>DELETE</http-method> <http-method>PUT</http-method> <http-method>HEAD</http-method> <http-method>OPTIONS</http-method> <http-method>PATCH</http-method> <http-method>GET</http-method> <http-method>POST</http-method> </web-resource-collection> <auth-constraint> <role-name>fedoraUser</role-name> <role-name>fedoraAdmin</role-name> </auth-constraint> <user-data-constraint> <transport-guarantee>NONE</transport-guarantee> </user-data-constraint> </security-constraint> <login-config> <auth-method>BASIC</auth-method> <realm-name>fcrepo</realm-name> </login-config>

   Note
   The "auth-constraint" element must contain the roles defined as your users (see below for jetty and tomcat).

4. Configure your web application container

...

• Tomcat

  • Create or edit your $CATALINA_HOME/conf/tomcat-users.xml file.  It has entries of the form
    

     <user name="principal" password="password" roles="role1, role2, ..." />

    where:

    • name is the user's login id (the principal)
    • password is the user's password
    • roles are the servlet roles they are assigned upon login;  tomcat 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 by the Policy Enforcement Point to perform actions.

    Sample tomcat-users.xml file that contains three users, two of whom are regular users, and the third of whom (fedoraAdmin) is a Fedora superuser:

    Code Block
    language xml title tomcat-users.xml
    <tomcat-users> <role rolename="fedoraUser" /> <role rolename="fedoraAdmin" /> <user name="testuser" password="password1" roles="fedoraUser" /> <user name="adminuser" password="password2" roles="fedoraUser" /> <user name="fedoraAdmin" password="secret3" roles="fedoraAdmin" /> </tomcat-users>

  • Configure your Tomcat login realm.
    Modify your file $CATALINA_HOME/conf/server.xml file to configure the login realm with the Fedora 4 webapp context:

    Code Block
    language xml title Tomcat server.xml Realm
    <Context> ... <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase" /> </Context>

    See the Tomcat Realms documentation for more details.
     

  • Configure your web.xml

    Modify fcrepo-webapp/src/main/webapp/WEB-INF/web.xml by uncommenting the security configuration

    Code Block

    <!--Uncomment section below to enable Basic-Authentication--> <security-constraint> <web-resource-collection> <web-resource-name>Fedora4</web-resource-name> <url-pattern>/*</url-pattern> <http-method>DELETE</http-method> <http-method>PUT</http-method> <http-method>HEAD</http-method> <http-method>OPTIONS</http-method> <http-method>PATCH</http-method> <http-method>GET</http-method> <http-method>POST</http-method> </web-resource-collection> <auth-constraint> <role-name>fedoraUser</role-name> <role-name>fedoraAdmin</role-name> </auth-constraint> <user-data-constraint> <transport-guarantee>NONE</transport-guarantee> </user-data-constraint> </security-constraint> <login-config> <auth-method>BASIC</auth-method> <realm-name>fcrepo</realm-name> </login-config>

    Note, the "auth-constraint" element must contain the roles previously defined in your server.xml file.
