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, using simple file-based users. Consult your web application server documentation for other ways to configure and manage users; Fedora can handle any principal passed to it by the servlet container, as provisioned by any of the container's supported authentication mechanisms.
The superuserrole is fedoraAdmin. This is comparable to the fedoraAdmin superuser role in Fedora 3, used for Fedora 3 API-M operations.

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>

- Embedded in Maven
The fcrepo-webapp Maven project includes jetty-maven-plugin. The property jetty.users.file sets the location of the jetty-users.properties file. Run the fcrepo-webapp server with the following system property:
- Embedded in Maven
-Djetty.users.file=/path/to/jetty-users.properties
See the Jetty Authentication documentation for more details.
Tomcat
- Create or edit your
$CATALINA_HOME/conf/tomcat-users.xml
file. It has entries of the form<user name="principal" password="password" roles="role1, role2, ..." />
where:
- name is the user's login id (the principal)
- password is the user's password
- roles are the servlet roles they are assigned upon login; tomcat allows you to specify any number of roles (or no role at all). Fedora currently supports two roles: fedoraAdmin, which is the superuser role, and has rights to do everything; and fedoraUser, which is a user role, and must be granted permissions to perform actions.
Sample tomcat-users.xml file that contains three users, two of whom are regular users, and the third of whom (fedoraAdmin) is a Fedora superuser:
Code Block language xml title tomcat-users.xml <tomcat-users> <user name="testuser" password="password1" roles="fedoraUser" /> <user name="adminuser" password="password2" roles="fedoraUser" /> <user name="fedoraAdmin" password="secret3" roles="fedoraAdmin" /> </tomcat-users>
Configure your Tomcat login realm.
Modify your file$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
