Can the following be achieved via configuration of control variables in the out-of-the-box Lifecycle Manager...

No. Whether an application supports password change requests through the IdentityIQ UI is not controlled by generic LCM workflow control variables. Password-change support depends on the application connector’s capabilities, password-management configuration, application settings, schema/support for password operations, policies, and QuickLink/user-interface configuration. The workflow may process or route a password-change request once launched, but it does not define which target applications support that operation. That capability must be configured at the application/connector and password-management layer. Mixing these layers would create a brittle design: workflow variables should govern execution behavior, while application configuration defines available account operations. Therefore, the proposed solution is not achievable merely by configuring out-of-the-box LCM workflow control variables.
