As of Fedora 4.7.4, the RBACL authorization modules is officially deprecated, and will not be included in future releases of Fedora. Subsequent Fedora releases will only include the WebAC authorization module.

This authorization delegate makes decisions based on the four basic roles of "metadata reader", "reader",  "writer", and  "admin".  These roles are assigned to principals on Fedora resources. Assigned roles are inherited through the repository tree until blocked by another assignment.

The role metadata reader has not yet been implemented.

This authorization delegate makes use of the Access Roles Module to assign and query roles in the repository.

Roles

Policy

The permissions granted to these roles are fixed. Rather than consulting any declarative policy, this authorization delegate has hard-coded role-permission assignments in the source code.

Configuring the Basic Role-Based Authorization Delegate

See Authorization Delegates for more information on how an authorization delegate is configured.

Edit your repo.xml file to configure the authentication provider.  The file should contain these three beans, as shown:

<bean name="modeshapeRepofactory" class="org.fcrepo.kernel.spring.ModeShapeRepositoryFactoryBean"
depends-on="authenticationProvider">
<property name="repositoryConfiguration" value="${fcrepo.modeshape.configuration:repository.json}" />
</bean>
<bean name="fad" class="org.fcrepo.auth.roles.basic.BasicRolesAuthorizationDelegate"/>
<bean name="authenticationProvider" class="org.fcrepo.auth.common.ServletContainerAuthenticationProvider">
    <property name="fad" ref="fad"/>
</bean>

Edit your repository.json file to enable an authenticated internal session between Fedora and ModeShape, so that the security section matches the example shown:

"security" : {
"anonymous" : {
"roles" : ["readonly","readwrite","admin"],
"useOnFailedLogin" : false
},
"providers" : [
{ "classname" : "org.fcrepo.auth.common.ServletContainerAuthenticationProvider" }
]
},
