Interactions with Other Modules

Fedora Configuration

It may be desirable--and in fact necessary for some modules--to disable/remove one of the default XACML policies which denies any interactions with the POLICY datastream to users without the "administrator" role.

This policy is located at: $FEDORA_HOME/data/fedora-xacml-policies/repository-policies/default/deny-policy-management-if-not-administrator.xml

Solr Searching Hook

In order to comply with XACML restrictions placed on objects, a hook is used to filter results that do not conform to a searching user's roles and name. This hook will not function correctly if the Solr fields for 'ViewableByUser' and 'ViewableByRole' are not defined correctly. These values can be set through the admin page for the module.
