A workflow is defined by a naming context (base DN) and a workflow element that define how the Sun OpenDS Standard Edition proxy should handle an incoming request. A workflow must be registered with at least one network group, but can be attached to several network groups.

A network group can point to several workflows when the naming context of the workflows are different. However, several network groups can point to the same workflow when the network group QOS policies are different, but the naming context of the workflow is the same.

Example 4-3
A Network Group Routing to Several Workflows

For example, if a Sun OpenDS Standard Edition proxy has the following network groups (as illustrated in Figure 4-2), where:

A search with bind DN **,l=uk,dc=sun,dc=com would be handled by Network Group 2 and sent to Workflow 2.

A search with bind DN **,dc=sun,dc=com would be handled by Network Group 3 and sent to Workflow 1 and Workflow 2.
