Calling Sequence

When the workflow engine needs to find an activity’s participants, it passes the property information defined within the workflow engine’s user interface to CA Identity Manager. This information includes the type of participant resolver to use (as follows, by order of precedence), the name of the participant resolver (with custom types), and optional user-defined data.CA Identity Manager then does the following:

• Calls the appropriate participant resolver, based on the specified participant type.
• Retrieves the participant list and passes it back to the workflow engine.

If multiple participant resolver types have been specified, CA Identity Manager selects one based on the following order of precedence:

• Custom type
• Role type
• Filter type
• Group type

CA Identity Manager uses the first participant resolver it finds and ignores the rest.

Note: The workflow engine interacts with the Participant Resolver API indirectly, through an CA Identity Manager-supplied script named IM Approvers. This script passes CA Identity Manager all the relevant property information defined within the workflow engine’s user interface, and CA Identity Manager passes the information to the Participant Resolver API. This script name must be included in the Resources properties of any workflow activity that requires an approval of a CA Identity Manager task.
