15.7. Permission Management
Just as Seam Security provides an Identity Management API to let you manage users and roles, it also provides a Permissions Management API to let you manage persistent user permissions — the
PermissionManager component.
15.7.1. PermissionManager
The
PermissionManager component is an application-scoped Seam component that provides a number of permission-management methods. It must be configured with a permission store before use. By default, it will attempt to use JpaPermissionStore. To configure a custom permission store, specify the permission-store property in components.xml:
<security:permission-manager permission-store="#{ldapPermissionStore}"/>
The following table describes each of the methods provided by
PermissionManager:
