There is no current plan to release a PeopleSoft connector for Identity Manager. The Professional Services team (PSO) uses either web services or connects directly to a database view to manage PeopleSoft identities.
Identity Manager version 7.0.1 and above is bundled with a Database connector which can be deployed to read and write to most of the databases in the market so it should be able to write/create PeopleSoft identities as well.
Please contact Professional Services
for more information on how to integrate with PeopleSoft.
