Managing access control with external security managers
IBM® WebSphere® Portal externalizes roles and uses access control to control role membership. From the perspective of the external security manager, these externalized roles contain only one permission: membership in the role. WebSphere Portal always determines the permissions associated with each role.
About this task
For example, if you externalize the Editor@Market News Page role, you must use the external security manager to edit the access control for that role. WebSphere Portal still determines the permissions that are associated with the Editor role type. Roles are always associated with a specific resource, so the role Editor@Market News Page contains specific permissions on the Market News Page only. Use the Resource Permissions portlet or the XML configuration interface to move resources back and forth from internal to external access control.
By default, externalized roles appear in the external security manager as Role Type@Resource Type/Name/Object ID. For example, Administrator@PORTLET_APPLICATION/Welcome/1_1_1G.
You can change this format to Resource Type/Name/Object ID@Role type. This format change groups the roles by resource name instead of by role type. For example, PORTLET_APPLICATION/Welcome/1_0_1G@Administrator. This format change is visible only when the roles are externalized. This change does not affect the way roles are displayed in WebSphere Portal.
The Administrator@VIRTUAL/wps.EXTERNAL ACCESS CONTROL/1 role is never affected by this format change. This role always appears with the role type Administrator.
